Barnes Ridge () is a ridge rising to over 1,200 metres (3,900 ft) and 7 miles (11 km) long, extending between Young Glacier and Ellen Glacier at the east side of the Sentinel Range, Ellsworth Mountains in Antarctica. Bounded by Rutford Ice Stream to the east and Arapya Glacier to the west.
It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1957–59, and named by the Advisory Committee on Antarctic Names for Stephen S. Barnes, scientific leader at Byrd Station in 1958.
