Cima Tosa is a mountain in the Brenta group (It.: Dolomiti di Brenta), a subgroup of the Rhaetian Alps in the Italian Region of Trentino-Alto Adige, with a reported height of 3,136 metres (10,289 ft). it is the second highest peak of the Brenta group in the southern limestone Alps after the Cima Brenta .

The height of the summit marked on the IGM maps is 3,173 m, which would make it the highest peak in the Brenta Dolomites. An electronic measurement campaign in 2015 determined the new height. The change could be linked to the partial melting of the ice cap that covers it. Being the second highest peak of the Brenta group also changed Cima Tosa's prominence making its prominence 589 m above the Bocca di Brenta.
