Booth Peninsula is a rocky peninsula, 4nmi long and 1nmi wide, of Antarctica, which projects west from the coast 3nmi southwest of Remenchus Glacier. It was mapped from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names for George H. Booth, an air crewman on the Operation Highjump seaplane commanded by D.E. Bunger which landed in this area and obtained aerial and ground photographs of this ice-free region.
