Sims Island is a small but conspicuous, largely ice-free, volcanic island lying south of Smyley Island, between the Rydberg Peninsula and Case Island, in the southern part of Carroll Inlet, off the coast of Palmer Land in the Bellingshausen Sea, Antarctica. It was discovered by pilot Ashley Snow of the United States Antarctic Service Expedition (1939–1941) on an aircraft flight on 22 December 1940. It was named for Lieutenant L.S. Sims of the United States Marine Corps (USMC), a surgeon on the expedition.
