多特森冰架是南极洲的冰架，位于玛丽伯德地沿岸，处于马丁半岛和熊号半岛之间，阔约50公里，美国地质调查局根据1947年1月的高空照片把该冰架绘制于地图中。

Dotson Ice Shelf is an ice shelf about 30 miles (50 km) wide between Martin Peninsula and Bear Peninsula on the coast of Marie Byrd Land in Antarctica. It was first mapped by the U.S. Geological Survey from air photos obtained by U.S. Navy Operation Highjump in January 1947, and was named by the Advisory Committee on Antarctic Names for Lieutenant William A. Dotson, US Navy, formerly Officer in Charge of the Ice Reconnaissance Unit of the Naval Oceanographic Office, killed in a plane crash in Alaska in November 1964 while on an ice reconnaissance mission.
