The Pitcairn Islands, officially Pitcairn, Henderson, Ducie and Oeno Islands, are a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred miles of ocean and have a combined land area of about 18 square miles (47 km2). Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The inhabited islands nearest to the Pitcairn Islands are Mangareva, 688 km to the west, as well as Easter Island, 1,929 km to the east.

The complement of HMS Bounty, the Royal Navy ship on which a historic mutiny occurred in the south Pacific on 28 April 1789, comprised 46 men on its departure from England in December 1787 and 44 at the time of the mutiny, including her commander Lieutenant William Bligh. All but two of those aboard were Royal Navy personnel; the exceptions were two civilian botanists engaged to supervise the breadfruit plants Bounty was tasked to take from Tahiti to the West Indies. Of the 44 aboard at the time of the mutiny, 19 were set adrift in the ship's launch, while 25, a mixture of mutineers and detainees, remained on board under Fletcher Christian. Bligh led his loyalists 3,500 nautical miles to safety in the open boat, and ultimately back to England. The mutineers divided—most settled on Tahiti, where they were captured by HMS Pandora in 1791 and returned to England for trial, while Christian and eight others evaded discovery on Pitcairn Island.
