The Dott Ice Rise is an ice -Rise in West Antarctica. The peninsula -like, almost completely covered by ice elevation is about 20 nautical miles ( 37 km) long and extends east of the Heritage Range, the southern part of the Ellsworthgebirges, to the ice-filled bay Constellation Inlet on the southwestern edge of the Ronne Ice Shelf. It is connected by the isthmus Johnson Neck with the eastern side of Pioneer Heights. The Barrett nunataks are the only part of the Ice- Rises, which projects beyond the ice.

Dott ice rise was mapped by the United States Geological Survey as part of the acquisition of the Heritage Range in the years 1961-66 by site surveys and aerial photographs of the United States Navy. The U.S. Advisory Committee on Antarctic Names named the Ice- Rise by the geologists of the United States Antarctic Program Robert H. Dott, who on the Chilean research station Bernardo O'Higgins as supreme representative of the United States worked on site in the summer of 1961-62.
