The Ammer Valley Railway (Ammertalbahn) runs through the German state of Baden-Württemberg, connecting the university town of Tübingen with Herrenberg in the Böblingen district. It mostly runs through the valley of the Ammer river.

The Royal Württemberg State Railways put the line into operation in 1909 and 1910. In 1966, Deutsche Bundesbahn stopped passenger traffic between Entringen and Herrenberg. The Gültstein–Herrenberg section was taken out of service and dismantled in the 1960s and 1970s. Since 1999, the entire length of the line has been reactivated for local passenger services. From 2019 to 2022, the line was electrified and partially double-tracked.
