Gambacorta Peak (84°2′S 56°3′W / 84.033°S 56.050°W / -84.033; -56.050 (Gambacorta Peak)) is a peak 1,840 metres (6,040 ft) high, standing 4 nautical miles (7.4 km; 4.6 mi) east of Mount Kaschak in the southern Neptune Range, Pensacola Mountains, Antarctica.

Gambacorta Peak was mapped by the United States Geological Survey from surveys and United States Navy air photographs from 1956 to 1966. It was named by the United States Advisory Committee on Antarctic Names for Captain Francis M. Gambacorta, captain of the USS Wyandot that transported the party which established Ellsworth Station at the outset of the International Geophysical Year. Unloading at the station site on the Filchner Ice Shelf began January 29, 1957.

The Antarctic Plateau is to the east. Nearby features include Mount Harper, Mount Kashak and Mount Bragg to the southwest, Mount Feldkotter to the south, and Patrick Nunatak, Seay Nunatak and Hill Nunatak to the east.
