Bundesautobahn 24 (translates from German as Federal Motorway 24, short form Autobahn 24, abbreviated as BAB 24 or A 24) is an autobahn in northern Germany that connects the large metropolitan regions of Hamburg and Berlin.

It was one of the three transit access roads to West Berlin during the Cold War.

Planning for the autobahn began as far back as the 1930s; before World War II numerous bridges and sections of roadside shoulder were built between Hamburg and Berlin.

The German divide, however, put a hold on further work and it was not until 1978 that construction was resumed, carried out by a GDR work force and paid for by West Germany.

Most pre-war bridges could not be used, however, and were replaced by new structures.
