Cape Longing is a rocky cape on the east coast of Graham Land, Antarctica, forming the south end of a large ice-covered promontory which marks the west side of the south entrance to Prince Gustav Channel. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902, and so named by him because from the position of his winter hut on Snow Hill Island the cape lay in the direction of his "land of longing" which he was anxious to explore.
