Piz da la Margna (3,158 m) is a mountain in the Bernina Range of the Alps, overlooking Lake Sils in the Swiss canton of Graubünden.

It lies to the south-east of the Maloja Pass at the south-western end of the Engadin valley.

Ascents can be made from Maloja via the north ridge (F); a slightly easier route is via the Val Fedoz and the east flank.

The south-east ridge from the Fuorcla da la Margna (AD, IV) was first climbed by Hans Frick, Christian Zippert and Hans Casper on 14 August 1918.

[2] The first recorded ‘tourist’ ascent of the mountain was made by J. Caviezel, Krättli, Robbi and Zaun in June 1857.
