The Argentine Islands are a group of islands in the Wilhelm Archipelago of Antarctica, situated southwest of Petermann Island, and northwest of Cape Tuxen on Kyiv Peninsula in Graham Land. They were discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for the Argentine Republic, in appreciation of that government's support of his expedition.
