Captain Peter Heywood was a British Royal Navy officer who was on board HMS Bounty during the mutiny of 28 April 1789. He was later captured in Tahiti, tried and condemned to death as a mutineer, but subsequently pardoned. He resumed his naval career and eventually retired with the rank of post-captain, after 29 years of honourable service.

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.
