Blankenfelde station is on the Berlin–Dresden railway in the locality of Blankenfelde in the municipality of Blankenfelde-Mahlow in the district of Teltow-Fläming in the German state of Brandenburg. The station consists of two sections that are structurally separate from each other. One section is located just south of the Karl-Marx-Straße level crossing and consists of an island platform for regional and long-distance services. The other section lies north of Karl-Marx-Straße and is the southern terminus of Berlin S-Bahn line S2. On the official S-Bahn maps its name is styled Blankenfelde to avoid possible confusion with Blankenfelde locality in the Pankow district in northern Berlin.

The Berlin–Dresden railway is a double track, electrified main line railway in the German states of Berlin, Brandenburg and Saxony, which was originally built and operated by the Berlin-Dresden Railway Company. It runs from Berlin through the southern Teltow countryside and then between Lower Lusatia and Fläming Heath through Elsterwerda and the Großenhainer Pflege countryside to Dresden.
