The Signalkuppe (in German, pronounced seeg-nall-koo-pay) also known as Punta Gnifetti (in Italian) (4,554 m) is a peak in the Pennine Alps on the border between Italy and Switzerland. It is a subpeak of Monte Rosa. The mountain is named after 'the Signal', a prominent gendarme atop the east ridge, named Cresta Signal.

The first ascent was made by Giovanni Gnifetti, a parish priest from Alagna Valsesia, together with J. Farinetti, C. Ferraris, C. Grober, J. and G. Giordiano and their porters on 9 August 1842.

The highest hut in Europe, the Margherita Hut (Capanna Marguerita, named after Italy's Queen consort Margherita of Savoy) lies on the summit of the mountain. Work started in 1890, supported by the Italian crown, and Queen Margherita opened it in 1893. The new hut, effectively a high-altitude Faraday cage, is clad in sheet copper to shield against unwanted electrical fields.

The Signalkuppe (Punta Gnifetti) is connected to the Zumsteinspitze (Italian: Punta Zumstein) (German: Zumsteinspitze) by the high-alpine glaciated saddle Colle Gnifetti.
