2355 m.) (Italian: Passo della Greina, Romansh: Pass Crap) is a high mountain pass across the western Lepontine Alps, connecting Sumvitg in the canton of Graubünden in Switzerland and Olivone in the canton of Ticino.

Greina is also a high plateau (Plaun la Greina) lying east of the pass, it is an alluvial site of national importance.

This compensation called Landschaftsrappen is augmented by a tax for powerplants.
