Siple Island is a 110 km (68 mi) long snow-covered island lying east of Wrigley Gulf along the Getz Ice Shelf off Bakutis Coast of Marie Byrd Land, Antarctica. Its centre is located at 73°51′S 125°50′W.

Its area is 6,390 km² (2,467 sq mi) and it is dominated by the dormant shield volcano Mount Siple, rising to 3,110 m (10,203 ft) — making Siple the 15th ranking island in the world in terms of maximum elevation.

The feature was first indicated as an island on U.S. Geological Survey (USGS) maps compiled from ground surveys and U.S. Navy air photos, 1959–65.Island was visited by USCG Icebreaker, Polar Sea, in 1984 during Operation Deep Freeze. USCG serviceman, James F. Woodruff, was first to record footing on the island.

The island and the mountain were named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1967 in honour of the American Antarctic explorer Paul A. Siple (1909–1968), a member of Admiral Byrd's expeditions.
