Marescot Ridge () is a ridge consisting of numerous ice-covered hills, the highest being Crown Peak (1,185 m) at the south end of the ridge. Located 2 nautical miles (3.7 km) inland from Marescot Point along the northwest coast of Trinity Peninsula. This ridge was probably observed by Captain Jules Dumont d'Urville on February 27, 1838, when he named nearby "Cap Marescot" (now Marescot Point). Following its 1946 survey, the Falkland Islands Dependencies Survey (FIDS) gave the name Marescot Ridge to this ridge, thinking it to be the coastal feature named by d'Urville. The name Marescot has been retained for both the ridge and the nearby point.
