Tongue Peak is a peak rising to about 2,450 m between Holdsworth Glacier and Scott Glacier, 3 nautical miles (6 km) west-northwest of Mount Farley, in the Queen Maud Mountains. The peak was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy aerial photographs, 1960-64. It was geologically mapped by a United States Antarctic Research Program (USARP)-Arizona State University field party, 1978–79, and was named by geologist Scott G. Borg, a member of the party.
