The Ellen Glacier is a glacier in the central Sentinel Range of the Ellsworth Mountains of Antarctica. It drains the eastern slopes of Mount Anderson and Long Gables and flows generally southeast for 22 nmi to Barnes Ridge, where it leaves the range and enters the south flowing Rutford Ice Stream. It was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Lieutenant Colonel Cicero J. Ellen of the U.S. Air Force, who was in command of many of the air operations when the South Pole Station was established by air drop in the 1956–57 season.
