Southampton were originally formed in 1885 as '''St. Mary's Young Men's Association FC
, before adopting the name Southampton St. Mary's
when the club joined the Southern League in 1894. After they won the Southern League title in 1896–97, the club became a limited company and changed their name to Southampton FC'''. Portsmouth was founded in April 1898 and joined the
Southern League in
1899. The first match between the two clubs came in a friendly at Portsmouth's
Fratton Park ground on 6 September 1899. The match was won "on their merits" 2–0 by Portsmouth, with goals from
Dan Cunliffe (formerly with
Liverpool) and
Harry Clarke (formerly with
Everton). Southampton and Portsmouth first played each other in the
Southern League in April 1900, with Portsmouth winning 2–0 twice in three days. The teams met regularly in the Southern League, and in the early years of the 20th century were rivals for the league title. During the pre Football League era both teams enjoyed title success with Southampton winning the Southern League on six occasions 1897, 1898, 1899, 1901, 1903 and 1904. with Portsmouth enjoying two Southern League Titles in 1901 and 1920 and three Western League titles in 1901, 1902 and 1903 The first of four South Coast derbies in the
FA Cup took place on 13 January 1906. Because of the large crowd expected for the first FA Cup meeting between the two rivals, the local registrars in both towns postponed voting in the
1906 general election until the following week. The match at
The Dell was attended by a capacity crowd of 14,000 and the Portsmouth fans, together with their players, did their best to unsettle the inexperienced Southampton goalkeeper,
Bill Stead, who was making only his second first team appearance. Stead, however, showed few signs of nerves and produced a "phlegmatic performance", restricting Portsmouth to a single goal from
Dan Cunliffe, while the Saints scored five and eventually progressed to
the last eight, where they lost 3–0 at
Liverpool. For the
1920–21 season, both teams were admitted to the third division of the
Football League (together with the majority of the Southern League First Division sides). The first Football League game between the two clubs was on 11 September 1920, with Southampton winning 2–0. After two seasons in the
Third Division, Southampton were promoted as champions in
1922. Portsmouth joined them in the Second Division in
1924 and were promoted to the
First Division in
1927, becoming the first southern club outside of London to reach the top tier of English football. Up to this time the teams had met ten times in the Football League, with Saints winning four, Pompey three and three draws. From 1927 until 1960 Portsmouth enjoyed a much-superior league position to their neighbours, winning the FA Cup in
1939 and back-to-back League titles in
1948–49 and
1949–50, until
1960, when Southampton gained promotion back to the
Second Division, Portsmouth having been relegated from the First Division the
previous season. The first match in all Competitions since 1927 did not end well for Portsmouth who were on the wrong end of a 5–1 scoreline at
The Dell. Both teams enjoyed derbies for eight consecutive seasons while both were in the
Second Division. It would not be until
1974–75 that the two would met in the league again when Southampton were relegated from the
First Division the previous season. A notable victory for Southampton included the 1–0 win on 6 April 1976 which is to date the last league victory for Southampton at
Fratton Park. In 1978, Southampton were promoted back to the First Division where the derby occurred only once in the FA Cup in 1984. In 1987, Portsmouth gained promotion to First Division which ensured that the South Coast derbies would return for the first time in the league since 1976. A notable victory for Portsmouth coming in a 2–0 win at
The Dell in an otherwise forgettable return to top flight football during the
1987–88 First Division season During the period from 1988 to 2003 the derby only happened once in the form of an FA Cup match at
The Dell in 1996. Events such as the death of Portsmouth goalkeeper
Aaron Flahavan, a Southampton-born footballer whose brother
Darryl had played for Southampton (and would later play for Portsmouth), occasionally brought the fans together. Portsmouth were crowned champions of
Division One in 2003 which signaled not only Premiership and a return to the top flight but it reignited the clubs' rivalry – the first time the two teams had met in regular league competition since the
1987–88 First Division season. Both teams had a home victory in a brief return of derby games during the
2003–04 and
2004–05 seasons. The rivalry was galvanised with the appointment of
Harry Redknapp as Southampton manager in December 2004, just days after he had resigned as manager of Portsmouth, and less than a month after the Saints had beaten Portsmouth at St Mary's Stadium. The following month, the Saints were drawn against and defeated their rivals in a fiery
FA Cup match, with former Portsmouth striker
Peter Crouch (who would go on to rejoin Portsmouth in 2008) scoring the decisive penalty in the last minute of the match. However, Portsmouth struck back in the next league encounter between the rivals, with Portsmouth registering a 4–1 win at
Fratton Park, which was their second biggest after the 1919 5–1 victory. It turned out to be Redknapp's only return to the ground with the club. Southampton were subsequently relegated from the Premiership on the final day of the 2004–05 season, ending their 27-year run in the top flight of English football. Redknapp caused more controversy when he left Southampton and returned to Portsmouth later in 2005 and enjoyed success. During the seven years that followed it was Portsmouth's time to hold the higher league position in the Premier League while Southampton were in the
Championship and then in
League One. Portsmouth won the
FA Cup again in
2008 under Redknapp, whilst in
2009, Southampton were again relegated, this time to
League One. The two sides met in a fierce FA Cup match at St Mary's in 2010 which Portsmouth came out 4–1 victors again and went on to reach the
FA Cup final that season, due to financial problems Portsmouth were docked 10 points by the FA and were in turn relegated to the Championship for the 2010–11 season. Southampton were in
League One during the 2010–11 season so it would not be until the next season South Coast Derby football would return. The matches played during the
2011–12 season both ended as draws, but the club's fortunes differed considerably, with Southampton gaining promotion to the Premier League and Portsmouth once again going into administration and being relegated to League One. In September 2019, Southampton were drawn against Portsmouth in the
EFL Cup for their first meeting in seven years. Unsurprisingly, Southampton comfortably beat their rivals, who were 51 places below them in the football pyramid, by 4 goals to 0. Southampton had a disastrous
2024–25 season in which they only managed to get two wins and were the earliest team relegated from the Premier League. During the same season, Portsmouth successfully finished mid-table in the Championship, to set up the first South Coast Derby in the league for 13 years for the 2025–26 season. The first derby came in September 2025 at St Mary's with a goaless draw. == Harry Redknapp ==
