Among the fourteen British Overseas Territories, eight – Akrotiri and Dhekelia, the British Antarctic Territory, the British Indian Ocean Territory, the Falkland Islands, Gibraltar, the Pitcairn Islands, Saint Helena, Ascension and Tristan da Cunha, and South Georgia and the South Sandwich Islands – recognise and perform same-sex marriages. In the Sovereign Base Areas of Akrotiri and Dhekelia, only British military and civilian personnel can enter into same-sex marriages and civil partnerships.

The five Caribbean territories do not recognise same-sex unions. Three specify the right of opposite-sex couples to marry in their constitutions, though they have no laws prohibiting same-sex marriage. Same-sex civil partnerships are performed in the Cayman Islands and Bermuda.
