On the Reeperbahn at Half Past Midnight (German: Auf der Reeperbahn nachts um halb eins) is a 1954 West German comedy drama film directed by Wolfgang Liebeneiner and starring Hans Albers, Heinz Rühmann and Fita Benkhoff. The film is set in Hamburg and was one of two 1950s films starring Albers attempting to emulate the success of his 1944 hit Große Freiheit Nr. 7. The film takes its name from the 1912 song of the same name and is not a remake of the 1929 silent film of the same title. A further version was made in 1969 with Curd Jürgens.

It was shot at the Tempelhof Studios in West Berlin and on location around Hamburg, including St. Pauli and Cuxhaven as well as on Heligoland. The film's sets were designed by the art directors Willi Herrmann and Heinrich Weidemann.
