Gäufelden is a municipality in the administrative district of Böblingen, in the German state of Baden-Württemberg.

The railway station is served every two hours by regional express trains to Singen (in the opposite direction to Stuttgart Hauptbahnhof), by regional trains to Freudenstadt Hauptbahnhof or Rottweil, which also share every two hours in Eutingen im Gäu, and by individual regional trains to Herrenberg (in the opposite direction to Bondorf (b Herrenberg)).

In the evenings from Monday to Friday, a pair of trains on the S 81 line of the Karlsruhe Stadtbahn, which otherwise ends in Eutingen im Gäu, will also be tied through to Herrenberg, which also stops in Gäufelden.

The municipality was founded July 1, 1971 by the voluntary merger of the previously independent villages of Nebringen, Öschelbronn and Tailfingen.

Each district retains a Rathaus (town hall), but the administration is centralized in Öschelbronn.
