The Stuttgart-Rohr–Filderstadt line is an electrified, and mostly double-track line main railway in the German state of Baden-Württemberg. It branches in the Stuttgart district of Rohr from the Gäu Railway (Gäubahn) and runs via Oberaichen, Leinfelden, Echterdingen and Stuttgart Airport to Bernhausen, a district of Filderstadt. It is now part of the Stuttgart S-Bahn.

The Rohr–Echterdingen section was built as an unemployment relief project in 1920 by the Deutsche Reichsbahn (DR) to connect with the Stuttgart-Möhringen–Neuhausen auf den Fildern railway, that had been built by the private Filder Railway Company (Filderbahn-Gesellschaft) to create a better link with the DR network. The line was opened on 1 October 1920, with services running through to Neuhausen. This allowed passenger trains to run through without changing in Degerloch. Services from Echterdingen to Filderstadt were operated by Stuttgart Tramways (Stuttgarter Straßenbahnen, SSB) from 1920 and the Tramways took over the ownership of the line in 1934. In 1928 a branch line was opened from Leinfelden to Waldenbuch called the Siebenmühlentalbahn (Siebenmühlen Valley Railway).

A track was laid in 1934 between Echterdingen and Bernhausen for the construction of the A8 and Stuttgart Airport. It was extended towards Denkendorf to take construction material along the autobahn as it was built and it also supplied construction materials and goods for the construction of the airport, which was completed in 1939. The route of the line was diverted to the east of Echterdingen station to Bernhausen in 1937 to run south of the airport area. The current S-Bahn route, however, largely follows the former construction siding.
