The history of Arka dates back to 1929, when a group of workers of the
Port of Gdynia founded
Klub Sportowy (Sports Club) Gdynia (abbreviated KS Gdynia). In 1932, a new stadium of KS was opened at
Polanka Redłowska. This location was used by the club until 2000. In 1934,
Klub Sportowy Kotwica (Sports Club Anchor) was registered. Both team existed until 1939. In 1949,
Rybacki Klub Sportowy ("Fishermen Sports Club") MIR was formed. Three years later, its name was changed to
Klub Sportowy Kolejarz-Arka Gdynia. In 1953, the team for the first time won promotion to the third level of Polish football. In 1959, Arka's U-19 became Polish runner-up, and in 1960, after a dramatic game vs.
Hutnik Kraków, Arka won promotion to the Second Division. In 1964, Arka merged with Doker Gdynia, to form Morski Związkowy Klub Sportowy (MZKS; "Maritime United Sports Club") Gdynia. In 1972, its name was changed into Arka. Two years later Arka won promotion to the
Ekstraklasa. Relegated after one year, Arka returned to the top level in 1976. In 1979 Arka, managed by
Czesław Boguszewicz, became the first team from Polish
Baltic Sea coast to win the
Polish Cup. In the final game, which took place in
Lublin, Arka beat
Wisła Kraków 2–1. In its
UEFA Cup Winners' Cup debut, Arka lost to Bulgarian side
PFC Beroe Stara Zagora (3–2, 0–2). In 1982, Arka was relegated from the top level, to return there in 2005. In the
1982 World Cup in
Spain, Arka's
Janusz Kupcewicz was among top players of Polish national team, which won bronze medal. In the 1980s and 1990s, Arka played either in the third or second division, with a number of promotions and relegations. In 2001, after six years in the third level, Arka again won promotion to the second division, and in 2005, the team returned to Ekstraklasa. In 2011, the City of Gdynia completed the construction of a new
stadium, located on Olimpijska Street. On 19 February 2011, Arka tied 1–1 with
Beroe Stara Zagora in a friendly game to commemorate the opening of their new venue. That year, Arka were relegated from the top level. In 2016, Arka was promoted to the top level again after taking first place in the I liga. Soon after getting promoted, Arka won the
Polish Cup for the second time, and the
Polish Super Cup twice: in 2017 and 2018. == Honours ==
