Grenzallee is a station on the Berlin U-Bahn line U7. It is located on Buschkrugallee, Neukölln, spanning the junctions with Grenzallee and the A100 motorway. The station was opened in 1930 and built by Alfred Grenander.

When the station opened in 1930 it was the last passenger station on Line C^I, which was first extended to the south in 1963. ^[1]

The station was not initially directly affected by the Second World War. However, it was out of operation for a period from 1944 to 1945, when the Berliner Verkehrsbetriebe (BVG) shortened the route of Line C to terminate at Bergstraße (now Karl-Marx-Straße), renting the tunnel and two stations to the south for use by the arms company Henschel-Flugwerke.
