Early years (1870–1901) Port Adelaide was formed on 12 May 1870 as a joint football and cricket club, created by locals to benefit the growing number of workers associated with the surrounding wharves and industries of
Port Adelaide. The first training session of the newly formed club took place two days later. Prior to 1877, football in
South Australia was yet to be formally organised by a single body and as a result there were two main sets of rules in use across the state. In an effort to create a common set of rules, In 1879, the club played reigning
Victorian Football Association (VFA) premiers
Geelong at Adelaide Oval in what was Port Adelaide's first game against an interstate club. It played its first match outside of South Australia two years later, when it travelled to Victoria to contest a game against the
Sale Football Club. It later contested
the SAFA's first grand final in 1889, as Port Adelaide and Norwood had finished the season with equal minor round records. Norwood went on to defeat Port Adelaide by two goals. Port Adelaide won its second SAFA premiership the following year, and went on to be crowned "
Champions of Australia" for the first time after defeating VFA premiers
South Melbourne. As the 1890s continued, Australia was affected by a severe depression that forced many players to move interstate to find work. This exodus translated into poor on-field results for the club. By 1896, the club had finished last on-field, with the season being described as "the worst in the record of football in South Australia" during a club meeting. The following year, Port Adelaide rebounded to win their
third premiership, with significant credit for the achievement given to club secretary Henry Hills.
Stan Malin won Port Adelaide's first
Magarey Medal in 1899. During the 19th century, the club had nicknames including the Cockledivers, the Seaside Men, the Seasiders and the Magentas. In 1900, Port finished bottom in the six-team competition, which it would not do again in any professional league until 2024. After finishing the
1902 season on top of the ladder, Port Adelaide was disqualified from their finals game against after the club disputed the use of an unaccredited umpire. The 1902 SAFA premiership was subsequently awarded to
North Adelaide after they defeated South Adelaide in the Grand Final a week later. Port Adelaide offered to play North Adelaide after the conclusion of the season, but the SAFA refused to allow it. In the early 1910s, Port Adelaide became a consistent premiership contender, setting up the club to win three more Championships of Australia. Port Adelaide won the South Australian Football League (SAFL) premiership in 1910 defeating
Sturt 8.12 (60) to 5.11 (41) in the Grand Final. The club would go on to defeat
Collingwood for the
1910 Championship of Australia title, and defeated both
Western Australian Football League (WAFL) premiers
East Fremantle and a combined WAFL team in a pair of exhibition matches. Although Port Adelaide had success in the minor rounds the following two seasons, losing only a single game in 1911 and going undefeated in 1912, it was knocked out of contention by
West Adelaide both times. The club won the SAFL premiership in 1913, losing only two games during the minor round and defeating North Adelaide in the Grand Final. They also defeated
Fitzroy for the
1913 Championship of Australia. The
1914 Port Adelaide Football Club season is unique in SANFL history, being the only occasion in which a team has gone undefeated. The club won all its pre-season matches, won all fourteen SAFL games and the
1914 SAFL Grand Final where it held North Adelaide to a single goal for the match 13.15 (93) to 1.8 (14). It also became the first to score over 1000 points during the minor round. The club met
Victorian Football League (VFL) premiers
Carlton in the Championship of Australia, defeating them by 34 points to claim a record fourth title. At the end of the 1914 season, a combined team from the six other SAFL clubs played Port Adelaide and lost to the subsequently-dubbed "Invincibles" by 58 points.
Two World Wars and the Great Depression (1916–1949) flag pennant presented to them the following year at
Adelaide Oval Port Adelaide's early-century success was hindered by
World War I. During the war, the club lost three players as casualties. Port Adelaide struggled to replicate its past success after the war. Despite winning the 1921 premiership under the captaincy of
Harold Oliver, the club would go on to finish seventh in 1923, their worst competition finish since 1900. During 1939,
Bob Quinn, in his third year as a player for the club, coached the team to a Grand Final win over
West Torrens. Many Port Adelaide players also enlisted for military service during this time. The club suffered six player casualties during the war. The joint club played in all three Grand Finals during this period, winning
the 1942 instalment, but losing the
1943 and
1944 editions to the Norwood-North Adelaide combination. While normal competition resumed in 1945, Port Adelaide was unable to regain its pre-war success in the rest of the decade. In particular, it lost the
1945 SANFL Grand Final after a remarkable comeback from West Torrens. The 'All Australian', predecessor to the modern 'All-Australian' team, was created by
Sporting Life magazine in 1947, with Bob Quinn being named in the side as captain. During the 1950s, Port Adelaide re-established itself as a perennial contender, winning seven premierships. At the end of the 1949, having missed two finals series in a row, the club's committee sought out a coach that could win the club its next premiership. Following a failed attempt to obtain
Jim Deane, the decision was made to appoint
Fos Williams, a
rover from West Adelaide. In his second season as player-coach in 1951, Williams led the club to their first standalone premiership in 12 seasons, defeating North Adelaide by 11 points. In the 1951 post-season, Port Adelaide lost an exhibition match to reigning VFL premiers Geelong. In the mid-1950s, Port Adelaide and
Melbourne, often the premiers of South Australian and Victorian leagues respectively, played multiple exhibition matches at
Norwood Oval in contests that were likened to the Championship of Australia. Keith Butler, a scribe for
The Advertiser, described the 1955 match as "the fastest and most thrilling game seen under electric light". That year, the club won the premiership and equalled a national record of six consecutive Grand Final victories, having won each premiership from 1954 to 1959. Port Adelaide's premiership streak was brought to an end in the 1960 preliminary final with a 27-point loss to Norwood. Williams returned in 1962, and coached Port Adelaide to win three of the next four premierships. After the
1965 Grand Final, Port Adelaide's success was limited by the dominance of Sturt, which won seven premierships over this period under the leadership of
Jack Oatey. Despite playing in 6 of the next 10 grand finals, Port Adelaide failed to win another premiership in that span.
John Cahill, SANFL domination and AFL licence (1974–1996) One of Port Adelaide's leading players during the Fos Williams era was
John Cahill. After retiring from playing in 1973 and following the departure of Fos Williams to West Adelaide in 1974, he took over as coach and began another era of premiership success for the club. In 1976, Cahill took Port Adelaide to its first Grand Final under his leadership, facing Sturt. Sturt won in front of an official attendance of 66,897, the record for football in South Australia. The actual crowd was estimated at 80,000, much bigger than the official figure. The following year, Port Adelaide won the premiership to break a 12-year drought. outside
Adelaide Oval, unveiled 15 August 2015 The
1980 season was Port Adelaide's most dominant since 1914. The club completed its fourth ever 'Triple Crown', winning the premiership, Magarey Medal and having the SANFL's leading goalkicker in a single season. In his stead, Russell Ebert became coach in 1983. During his five years as coach, Port Adelaide made the finals three times, and achieved a win rate of above 55%. John Cahill returned as coach from the 1988 season, winning the premiership that year. He won a further five premierships, Two key events of the late 1980s were attempts by the VFL to further expand outside of Victoria and financial difficulties in the SANFL. In 1989, seven of the ten SANFL clubs were recording losses and the combined income of the SANFL and WAFL had dropped to 40% of that of the VFL. During May 1990, the SANFL clubs unanimously accepted a SANFL proposal to not enter a club from South Australia until 1993. Weeks later, Port Adelaide, suffering from a mixture of ambition and frustration, started secret negotiations with the newly renamed
Australian Football League (AFL) in the town of
Quorn for entry to the competition in 1991. When knowledge of Port Adelaide's negotiations to gain an AFL licence were made public, the other nine SANFL clubs called a crisis meeting to discuss options. Plans were made to kick Port Adelaide out of the SANFL should they succeed, and to prevent them from using
Football Park as a home ground. SANFL clubs urged Justice Olssen to make an injunction against the bid, which he agreed to. After legal action from all parties, the AFL agreed to accept the SANFL's bid to enter the composite team, which was named the
Adelaide Football Club. During December 1994, Max Basher announced that Port Adelaide had won the tender for the second South Australian AFL licence on the condition that a merger take place between two existing AFL clubs to keep the league at the club limit imposed by the AFL in 1993. As such, the licence would not be made available until at least 1996, and was not guaranteed. With a merger of the
Brisbane Bears and Fitzroy looming, the club was advised on 21 May 1996 by the AFL that they would take part in the
1997 AFL season.
AFL entry, Mark Williams and club debt (1997–2010) Following confirmation of their entry in 1997, the club began preparations to enter the league. John Cahill began the transition to the AFL, with
Stephen Williams, a son of Fos Williams, taking over the SANFL coaching position from midway through the 1996 season. As part of the inaugural squad, a total of twelve players were signed from other AFL clubs, including
1993 Brownlow Medallist and inaugural captain
Gavin Wanganeen. On 29 March 1997, Port Adelaide played its first AFL premiership match against Collingwood at the MCG. It won its first AFL game in round 3 against Geelong, and defeated cross-town rivals and eventual premiers Adelaide by 11 points in the first
Showdown in round 4. The club finished its first season 9th, missing the finals on percentage behind
Brisbane. Following the
1998 season, John Cahill retired from his coaching position. was Port Adelaide's first since joining the AFL. In 1999,
Mark Williams, another son of Fos Williams, took over as coach of Port Adelaide and led the club to many notable first achievements in the AFL over the next decade. The club earned a spot in the AFL finals for the first time in Williams' first season, and would go on to finish in the top four after the home-and-away season four consecutive times between 2001 and 2004, including three consecutive minor premierships. However, repeated eliminations from finals during this period eventually led to certain elements of the press calling Port Adelaide "chokers", as well as trucking magnate
Allan Scott in early 2004—who was the founder and owner of Scott's Transport, Port Adelaide's major sponsor—publicly calling for Williams' dismissal. The
2004 season saw Port Adelaide achieve national success. Between Round 12 and the end of the home-and-away season, the club would only lose a single game - claiming their third consecutive minor premiership. An exuberant Williams took to the field after the siren and ripped off his tie in a mock choking gesture, later exclaiming during his acceptance speech: "Allan Scott, you were wrong!" In 2007, the club qualified for the
grand final following a strong home-and-away season, where they were defeated by Geelong by an AFL record margin of 119 points, 24.19 (163) to 6.8 (44). Following their second grand final, Port Adelaide began experiencing financial troubles. By 2009, the club had accumulated a consolidated debt totalling $5.1 million and was unable to pay its players; they had lost $1.6 million the season before. The AFL delayed giving the club financial support, instead urging it to sort out deals with SANFL as a predecessor to any league support. On 20 May, Port were handed $2.5 million in debt relief by the SANFL, Plans for a re-merging of the two teams was rejected by the SANFL early during 2010, though they eventually signed off on the proposal during November 2010. The 2010 season saw Mark Williams step down as senior coach.
Independence and Ken Hinkley (2011–present) as its home ground for the first time since the
1976 SANFL season. On 9 September 2010,
Matthew Primus was appointed as the senior coach of the club for the next three years, following a stint as caretaker coach where he won five of seven games coached. 2011 saw the club's financial crisis come to a head. Due to the lack of financial reserves, the SANFL was unable to get a line of credit to cover Port Adelaide's future debts, prompting talks of a potential takeover. To bail out the club, AFL Chief executive Andrew Demetriou offered $9 million over the next three years, ahead of a planned move to the
Adelaide Oval. On-field, Port Adelaide finished sixteenth for the 2011 season with 3 wins, suffering record losses to Collingwood and
Hawthorn in Round 20 and 21. The following season, Matthew Primus stepped down from his position as coach, following a loss to . On 8 October 2012,
Ken Hinkley was announced as the new senior coach of the club. During the same week,
David Koch was named chairman of the club and numerous board members were replaced. The club finished the home and away season 7th on the ladder, qualifying for finals for the first time since 2007. Port won against Collingwood in an elimination final; they were defeated by Geelong the following week in a semi final. As the club entered the 2014 season, both Port Adelaide and Adelaide moved their home games from Football Park to the redeveloped Adelaide Oval. Amidst the change, Port Adelaide's license was transferred from the SANFL to the club for a sum of approximately $7 million, giving the club independent control of its operations for the first time in its history. Port Adelaide finished fifth on the ladder, with a win–loss record of 14–8. The club's season ended with a three-point loss to Hawthorn in the preliminary finals. The club saw another sustained period of strong home-and-away season results between 2020 and 2024. The club finished in the top four four times, including a fourth minor premiership in
2020, and a club-high 13 game winning streak in
2023. The club would also see
Ollie Wines become the first Port Adelaide player to win the
Brownlow Medal in
2021, winning the award with a record-equalling tally of votes. Despite strong home-and-away performances, the club was unable to qualify for the grand final during this period - suffering three preliminary final defeats, and a straight sets exit in 2023. In February 2025, the club announced that Hinkley's tenure as senior coach would conclude at the end of the 2025 season, and that assistant coach
Josh Carr would take over the position in 2026.
AFLW involvement was awarded the captaincy of
Port Adelaide's Women's team for its inaugural season in
2022 AFL Women's season 7. Prior to the creation of the AFLW, Port Adelaide undertook a big grassroots push to improve women's football in South Australia. The club made a host of announcements in early 2016 related to increasing participation in women's football. Due to logistical demands related to the club's China program, the club was unable to submit a bid for the
2017 AFLW season. The club subsequently attempted to enter a side in the
SANFL Women's League (SANFLW), but this approach was rejected by the
South Australian Football Commission. In May 2021, the
AFL Commission announced that the remaining four clubs without AFLW teams would be admitted to the competition by the end of 2023, with the clubs to bid for entry order. Port Adelaide's bid to enter the competition was successful, with the AFL Commission deciding all four clubs would debut in the AFLW in
2022 season 7.
SANFL presence (post–AFL entry) As part of Port Adelaide's initial bid for the 1994 AFL licence, the club was initially required to forgo any presence in the SANFL. After winning the tender for the licence, however, the SANFL requested that Port Adelaide field two teams in the SANFL and AFL, with the stipulation that both were completely separate to avoid granting any unfair advantage. For the first few years after their formation, the Port Adelaide Magpies were forced to train in
Ethelton, instead of using the upgraded
Alberton Oval training facilities. In response to financial trouble suffered by both Port Adelaide entities, the "One Port Adelaide Football Club" movement was launched by former players
Tim Ginever and George Fiacchi on 20 August 2010, in an effort to merge Port Adelaide's AFL and SANFL operations. A website was created that claimed 50,000 signatures were needed for the merger. On 16 November 2010, following approval from all nine SANFL clubs, the club formalised the off-field merger between the two entities. On 10 September 2013, Port Adelaide and the SANFL agreed to a model to allow all its AFL-listed players (not selected to play for Port Adelaide in the AFL) to play for the SANFL side. As part of the arrangement, the club lost its recruiting zones and could no longer field sides in the junior SANFL competitions, In 2018, Port Adelaide and the league jointly agreed that it would no longer field a team in the
SANFL Reserves competition. Port Adelaide initially still had success in the SANFL after accession into the AFL, with the Port Adelaide Magpies winning back-to-back Grand Finals in 1998 and 1999. However, the club would not make another grand final until the 2014 season, where it was defeated by Norwood by four points. Port Adelaide featured in two further grand finals against Sturt and Glenelg, though it would be defeated in both. The club did not field a team in the SANFL in the
2020 season due to AFL restrictions imposed during the
COVID-19 pandemic, though it re-joined the competition in 2021. In December 2023, the
Herald Sun reported that the club had applied for entry into the Victorian Football League (VFL) or a national reserves competition in 2025, thereby transitioning its reserves team out of the SANFL. By the end of 2024, the club negotiated changes with the SANFL to player recruiting rules, ensuring Port Adelaide's continued presence in the SANFL. == Club symbols and identity ==
