The Revillagigedo Islands or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately 390 kilometres (240 mi) southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and 720 to 970 kilometres (450 to 600 mi) west of Manzanillo. They are located around 18°49′N 112°46′W. Technically part of the Mexican state of Colima, the islands are under Mexican federal jurisdiction.
In July 2016, the Revillagigedo Archipelago were inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a national park of Mexico.
