Wager Island is an uninhabited island in Guayaneco Archipelago, a remote part of western Patagonia. Located 1,600 kilometres south of Santiago, the island is part of Capitán Prat Province of the Aysén Region, Chile. The island was the location of the Wager Mutiny, which took place in October 1741 after the wreck of the British warship HMS Wager.
