Prion Island is an island 2.4 km (1.5 mi) north-northeast of Luck Point, lying in the Bay of Isles, South Georgia. It was charted in 1912-13 by Robert Cushman Murphy, American naturalist aboard the brig Daisy, and so named because he observed prions on the island.

The island has been designated as a Specially Protected Area by the South Georgia Government, due to its rat-free status and breeding wandering albatrosses. Access is by permit, in that the island must be specifically named on the visit application and permit. A boardwalk with two viewing platforms was built in February/March 2008 to prevent erosion of the access gully and trampling of prion burrows. Wandering Albatross population counts are conducted annually. Because it is rat-free it is a breeding area for South Georgia pipits and burrowing petrels.
