Mount Tuck (78°29′S 84°50′W / 78.483°S 84.833°W) is a pyramidal mountain (3,560 m) at the head of Hansen Glacier, the summit of Doyran Heights in the Sentinel Range of Ellsworth Mountains, Antarctica. It surmounts Hansen Glacier to the north, Hough Glacier to the south and upper Dater Glacier to the west, and separated from Veregava Ridge to the northwest by Manole Pass.
The peak was first mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos from 1957 to 1959. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant John Tuck Jr., a U.S. Navy support leader at the South Pole Station in 1957.
