Henderson Island (formerly also San Juan Bautista and Elizabeth Island) is an uninhabited island in the south Pacific Ocean. It is part of the Pitcairn Island Group, together with Pitcairn, Oeno, and Ducie Islands. Measuring 9.6 by 5.1 kilometres (6.0 mi × 3.2 mi), it has an area of 37.3 km2 (14.4 sq mi) and is located 193 km (104 nmi) northeast of Pitcairn Island. It has poor soil and little fresh water, and is unsuitable for agriculture. There are three beaches on the northern end and the remaining coast comprises steep (mostly undercut) cliffs up to 15 m (50 ft) in height. In 1902, it was annexed to the Pitcairn Islands colony, which is now a British Overseas Territory.
