Leher Turnerschaft is a German football club from the Lehe district of Bremerhaven in the state of Bremen.

Founded in 1898, it plays in the Bremen-Liga in the fifth tier of the German football league system.

The ATSB actively promoted leftist political views built around class struggle and nationalism.

FSV avoided dissolution by abandoning the ATSB and reorganizing as Leher Turnerschaft.

In 2016–17, the team won the Bremen Cup for the first time, defeating Bremer SV 9–8 on penalties after a goalless draw in the final on 25 May.
