RSV Eintracht

RSV Eintracht won the NOFV-Oberliga Süd in 2026, and the title took them up to the Regionalliga Nordost. It came a year after the Brandenburg Cup, which they took by beating VfB 1921 Krieschow 1–0 in the final.

The cup run had a price attached. It sent the club into the DFB-Pokal in 2025/26, where 1. FC Kaiserslautern beat them 0–7. That was a heavy defeat for a side from the Brandenburg leagues, but the club went back to the Oberliga and won it.

The climb was steady rather than sudden. Titles in the Kreisliga Havelland-Mitte in 2009 and the Landesklasse Mitte in 2011 were followed by the Landesliga Brandenburg-Nord in 2014 and 2019, then the Brandenburgliga in 2020. Each of those moved the football side up a level.

Beyond the region, the name is better known for basketball. The club began on 2 August 1949 as TSG Einheit Teltow-Kleinmachnow, became BSG Elektronik Teltow in the 1950s and went back to TSG Teltow-Kleinmachnow 1949 after reunification. In 1998 it merged with Fußballjugend Kleinmachnow/Teltow to form RSV Eintracht Teltow-Kleinmachnow-Stahnsdorf. It took its present name in January 2016. The basketball department produced Joe Deister and Kevin Schaffartzik, and Vladimir Pastushenko coached there. The team was once known as the "TKS 49ers", the initials standing for Teltow, Kleinmachnow and Stahnsdorf. The registered seat is in Stahnsdorf, but the club carries all three towns.

Its nearest rival is Ludwigsfelder FC, and the local name for the fixture is the "Derby der Gegensätze", the Derby of Opposites.

Promotion also exposed a limit of the home ground. The pitch on Heinrich-Zille-Straße in Stahnsdorf does not meet Regionalliga requirements. Higher-division games are therefore played at the Preussenstadion in Berlin-Lankwitz, on Malteserstraße, which holds 3,000 people, 200 of them seated.
