Perim Island, island in the Bab el-Mandeb Strait off the southwestern coast of Yemen, to which it belongs. Although rocky and just 5 square miles (13 square km) in area, the volcanic island rises as high as 214 feet (65 m) and overlooks the strait near its narrowest point, about 16 miles (26 km) wide.

The importance of the small island grew with the advent of the Suez Canal, which connected the Mediterranean Sea and the Arabian Sea through the Red Sea and allowed global shipping routes to bypass the lengthy route around Africa. The Bab el-Mandeb Strait became a vital chokepoint along the new route and Perim Island’s position within the strait gave its occupier command over the eastern channel and a measure of control over its western channel. As steps were taken to begin the construction of the canal, the British seized the island in 1857 and established a coaling station, which later went bankrupt in 1935. Perim Island became part of independent Yemen (Aden) in 1967. It has a harbor on the southwestern shore, and a military airfield in the north. The United Arab Emirates built an airbase on the island during the Yemeni Civil War, but it withdrew its military from Yemen in January 2026. In September the island was captured by Houthi rebels.
