Merz Peninsula (72°15′S61°5′W) is an irregular, ice-covered peninsula, about 28 kilometres (15 nmi) long in an east–west direction and averaging 46 kilometres (25 nmi) wide, between Hilton Inlet and Violante Inlet on the east coast of Palmer Land, Antarctica. It was discovered and photographed from the air in December 1940 by the US Antarctic Service; during 1947 it was photographed from the air by the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground.
