The Dean Nunataks (74°31′S98°48′W) are a pair of nunataks lying about 6 miles (10 km) east-northeast of Mount Moses in the Hudson Mountains. They were mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1960–66, and were named by the Advisory Committee on Antarctic Names for William S. Dean of Pleasanton, Texas, who served as ham radio contact in the U.S.
