The Fils is a 63-kilometre-long (39 mi) river in Baden-Württemberg, Germany, a right tributary of the Neckar.

Its source is in the Swabian Alb hills near Wiesensteig. It flows through Geislingen (Steige) and Göppingen to join the Neckar east of Stuttgart, in Plochingen. Due to the contribution of the Fils, the Neckar is navigable from there.
