The Governor of Pitcairn^[1] is the representative of the British monarch in the Pitcairn Islands, the last remaining British Overseas Territory in the Pacific Ocean. Despite technically being under the authority of the colonial governor, Pitcairn has local autonomy.

Because of the dependency's small population (it peaked at 233 in the 1930s, and has since dwindled to 50), the British never considered it worthwhile to station a resident governor on Pitcairn. Instead, the Governor of Fiji doubled as governor of Pitcairn from 1898 onward. When Fiji became independent in 1970, the governorship of Pitcairn was transferred to the British high commissioner to New Zealand. The office is currently held by Iona Thomas.

Throughout the island's history, the authority of the British governor was almost never used. An exception was Governor Richard Fell's dismissal of Mayor Steve Christian, who was convicted in the Pitcairn sexual assault trial of 2004.
