Cape Mackintosh () is a low, ice-covered cape forming the north tip of Kemp Peninsula and the east entrance point to Mason Inlet, on the east coast of Palmer Land. Probably first seen by members of the United States Antarctic Service (USAS) who photographed a portion of Kemp Peninsula while exploring this coast from the air in December 1940. During 1947 the cape was photographed by the Ronne Antarctic Research Expedition (RARE), which in conjunction with the Falkland Islands Dependencies Survey (FIDS) surveyed it from the ground. Named by the FIDS after Neil A. Mackintosh (1900–74), British marine biologist, oceanographer, and authority on Antarctic whales; member of DI scientific staff from 1924 and Chief Scientific Officer, 1929–49; Deputy Director, National Institute of Oceanography (now Institute of Oceanographic Sciences), 1949-61.
