The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica.

Many peaks rise over 4,000 m (13,100 ft) and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.

The range was first sighted and photographed from the air on November 23, 1935, by Lincoln Ellsworth who in naming it recognized its prominent position as a landmark on an otherwise featureless ice surface.

The range was first visited and partially surveyed in January 1958 during the Sentinel Mountains Traverse led by Charles R. Bentley.

The entire range was subsequently mapped by USGS from aerial photography taken by the U.S. Navy, 1958-61.
