Frost Glacier (-67.0833°N 129°W) is a channel glacier flowing to the head of Porpoise Bay, Antarctica. It was delineated from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for John Frost, boatswain on the brig Porpoise of the United States Exploring Expedition (1838–42) under Charles Wilkes.
