The expression Chur S-Bahn (German: S-Bahn Chur) is used to describe two S-Bahn-style regional rail services focused upon Chur, the capital of the canton of Graubünden, Switzerland. Both of these S-Bahn services run on metre gauge lines, and are operated by the Rhaetian Railway, which also runs the line from Chur to Arosa in similar fashion.
