Santa Fe Island, also known as Barrington Island, is a small island of 24 square kilometres (9.3 sq mi) which lies in the middle of the Galápagos Archipelago in Ecuador. Visitor access is by a wet landing in Barrington Bay on the northeastern side of the island.

Admiral Samuel Barrington was a Royal Navy officer. Barrington was the fourth son of John Barrington, 1st Viscount Barrington of Beckett Hall at Shrivenham in Berkshire. He enlisted in the navy at the age of 11, and by 1747 had been promoted to post-captain. Barrington had good connections and was lucky to enlist at the right time, and proved to be an able officer.
