The South Georgia Survey was a series of expeditions to survey and map the island of South Georgia, led by Duncan Carse between 1951 and 1957. Although South Georgia had been commercially exploited as a whaling station during the first half of the 20th century, its interior was generally unknown, and maps were largely based on the original survey by James Cook, who first landed on the island in 1775. The South Georgia Survey was intended to make high-quality modern maps covering the entire island, and took place in four austral summer seasons: 1951–52, 1953–54, 1955–56, and 1956–57.
