The Tubbataha Natural Park, also known as the Tubbataha Reefs Natural Park, is a protected area of the Philippines located in the middle of the Sulu Sea. The marine and bird sanctuary consists of two huge atolls and the smaller Jessie Beazley Reef covering a total area of 97,030 hectares. It is located 150 kilometres southeast of Puerto Princesa, the capital of Palawan. The uninhabited islands and reefs are part of the island municipality of Cagayancillo, located roughly 130 kilometers to the northeast of the reef.
In December 1993, the UNESCO declared the Tubbataha Reefs National Park as a World Heritage Site as a unique example of an atoll reef with a very high density of marine species; the North Islet serving as a nesting site for birds and marine turtles. The site is an excellent example of a pristine coral reef with a spectacular 100-m perpendicular wall, extensive lagoons and two coral islands. In 1999, Ramsar listed Tubbataha as one of the wetlands of international importance. In 2008, the reef was nominated at New7Wonders of Nature.
