The Bernina Pass (el. 2328 m.) is a high mountain pass in the Bernina Range of the Alps, in the canton of Graubünden (Grisons) in eastern Switzerland. It connects the famous resort town of St. Moritz in the Engadin valley with the Italian-speaking Val Poschiavo, which ends in the Italian town of Tirano in Valtellina. The pass lies a few kilometres east of Piz Bernina. A lower pass is located west of the Bernina Pass, at 2,253 metres.
The Bernina Pass is crossed by road and rail, with a popular tourist train, the Bernina Express operating year-round between Chur and Tirano. The train crosses the lowest pass at 2,253 metres (at Ospizio Bernina) - it is the highest adhesion railway route in Europe. Lago Bianco, Lej Nair and Lej Pitschen are located on the pass.
