Cape Agassiz is the east tip of Hollick-Kenyon Peninsula, a narrow ice-drowned spur extending east from the main mountain axis of Antarctic Peninsula between Mobiloil Inlet and Revelle Inlet. The cape is the east end of a line from Cape Jeremy dividing Graham Land and Palmer Land. It was discovered in December 1940 by the United States Antarctic Service (USAS) who named it for W.L.G. Joerg, a geographer and polar specialist.
