Einthoven Hill is a hill at the south extremity of Avroleva Heights, 3 nautical miles (6 km) southwest of Mitchell Point on the east side of Brabant Island in the Palmer Archipelago, Antarctica. It was photographed by Hunting Aerosurveys Ltd in 1956–57, and mapped from these photos in 1959. It was named by the UK Antarctic Place-Names Committee for Willem Einthoven, the Dutch inventor of the electrocardiograph.
