St. Moritz railway station is a railway station in the resort town of St. Moritz, in the Swiss canton of Graubünden. It is the southern terminus of the Albula Railway line from Chur, and a northern terminus for the Bernina Railway line from Tirano in Italy. The station also serves as a terminus for local bus and Postbus services.

Hourly services operate on both the Albula and Bernina lines. Because these two lines operate with different types and levels of power supply, St Moritz is also a "Power supply switch" station (Systemwechselbahnhof).

The station is located at a height of 1,775 m (5,823 ft) above sea level and is the highest urban railway station in Switzerland.

The station came into operation in 1904. At this time St Moritz had already had its own electric tram service, Strassenbahn St. Moritz [de], since 1896 and there were plans to build a branch line to link the tram service to the new station. For financial reasons the short linking branch line was never built, however.
