Piz Terri is a mountain in the Lepontine Alps, located on the border between the cantons of Ticino and Graubünden.

At 3,149 metres above sea level it is the highest summit lying on the chain between Greina and Soreda Pass.

The lake named Laghet la Greina (0.183 km²[2]) is located not far from the summit, on the northwest side of the mountain, at an elevation of 2,585 metres.

Only a small glacier, named Glatscher dil Terri, lies at the base of the north face.

The normal route starts above Lake Luzzone at the Motterascio hut (2,171 metres), owned by the Swiss Alpine Club.
