Polonia Środa Wielkopolska is a football club in Środa Wielkopolska, Greater Poland Voivodeship. Polonia Środa competes in the III liga, group II. They play home games at the CSiR Stadion Średzki. The club also has field hockey and handball teams, and in the past had an interest in tennis.
Polonia Środa Wielkopolska is a sports club that was founded 1 October 1919. The first president was Adam Pankowski. In the second half of 1923, the club was caught up in financial trouble and in an attempt to rescue the club, chairman Tadeusz Mikolajczak changed the name from Polonia to Tabromik. The entity survived until 1930. On 28 November 1926, a group of former activists of the club convened a meeting to revive the club. President of the new entity was Stefan Kujawski, and the name was changed to Pogoń Środa Wielkopolska.
With the advent of World War II, the club suspended all activities. On 14 April 1945, a meeting was held which established the średzki Sports Club and on 9 June the name of Polonia was restored. In the 50s' the club name was changed - initially it was named Unia and later Kolejarz Środa Wielkopolska. In 1957, the name was changed back to Polonia.
Polonia quickly advanced to league three, in which it played until 1995. In the 1989–1990 season, players advanced to the Class of the District, and two years later to the macro-regional classes. As a result of the merger with Kotwica Kórnik, Polonia continued in the league starting from 1993, with their stay there lasting four years. From this period, the players managed to get the Polish Cup twice at the national level. In 2011, the club gained promotion to the III liga.[1]
