The Sora (German: Zayer or Zeier) is a right affluent of the Sava River in western Slovenia.

The Sora gathers its waters mainly from the Škofja Loka Hills.

[1] They flow together in Škofja Loka and continue the flow as the Sora for the next 9.2 kilometres (5.7 mi) until Medvode, where the Sora joins the Sava.

Its average discharge at the outflow is 25 cubic metres per second (880 cu ft/s).
