The Lacroix Nunatak is a 75 m high, ridge-like nunatak on a terminal moraine on the coast of the East Antarctic Adélieland . It rises immediately to the south of a zone of low rock ridges that protrude from the ice sheet 3 km southwest of Cape Margerie .
Participants of the British Australian and New Zealand Antarctic Research Expedition (BANZARE, 1929–1931) under the direction of the Australian polar explorer Douglas Mawson discovered him in 1931 in the mistaken belief that it was a 300 m high mountain peak. Mawson named this after the French mineralogist and geologist Antoine Lacroix (1863-1948). Aerial photos were taken during the US operation Highjump (1946–1947). Participants in a French expedition that lasted from 1949 to 1951 carried out a survey and set up an astronomical observation station here.
