FSV 유니온 푸르스텐발데

The roots of the club go back to SC Union 06 Oberschönweide Abt. Fürstenwalde, formed in 1919 as a section of Berlin-based SC Union 06 Oberschöneweide and adopted the name SC Union Fürstenwalde in 1927 after separating from the latter club. Union went through a number of name changes and merger after 1945 but eventually, in 1971, became SG Dynamo Fürstenwalde. Dynamo, affiliated to sports association SV Dynamo and associated with the Stasi, the secret police of East Germany, experienced some success at the second level of GDR football, the DDR-Liga. With the end of East Germany Dynamo was dissolved and Union reformed. In 2002 Union merged with Wacker Fürstenwalde to form the current club.

The club's recent rise through the league system began when it won promotion to the Brandenburg-Liga, the highest league in the state, in 2008. A championship at this level in 2011 took the club up to the NOFV-Oberliga Nord where it played until 2016, when another title there brought Union up to the Regionalliga Nordost for the first time.
