Hansen Glacier () is a tributary glacier 10 nautical miles (18 km) long, flowing northeast from Mount Tuck to join Dater Glacier, in the Sentinel Range, Ellsworth Mountains. First mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1957-59. Named by Advisory Committee on Antarctic Names (US-ACAN) for Hans Edvard Hansen, a cartographer in Oslo, Norway, who drew the first maps of this area, based on photographs taken by Viggo Widerøe as he flew over the area.
