Glover's Reef is a partially submerged atoll located off the southern coast of Belize, approximately 45 km (28 mi) from the mainland.

[1] A large spawning site for the endangered Nassau grouper (Epinephelus striatus) is located at the northeastern end of the atoll.

In 1996, it was designated by UNESCO as one of seven protected areas that together form the Belize Barrier Reef Reserve System (a World Heritage-listed site).

[11] It was opened in 1997 for the purpose of promoting and facilitating long-term conservation and management of the wider Belize Barrier Reef complex.

[1] A 1.2m ha site off the coast of Belize, comprising the nation’s offshore and barrier islands, has been designated an Important Bird Area (IBA) by BirdLife International because it supports significant populations of several resident, passage or breeding bird species, including white-crowned pigeons, red-footed boobies, roseate terns, Yucatan vireos, black catbirds, and golden-winged and cerulean warblers.
