Tarutao National Marine Park (Thai: อุทยานแห่งชาติทางทะเลตะรุเตา) consists of 51 islands located in the Andaman Sea, off the coast of Satun Province of Southern Thailand. The Tarutao National Marine Park consists of two island groups: Tarutao (Thai: หมู่เกาะตะรุเตา) and Adang-Rawi (Thai: หมู่เกาะอาดัง-ราวี), which are scattered from 20 to 70 kilometers distance from the southwestern most point of mainland Thailand. The park covers an area of 1,490 square kilometers (1,260 ocean, 230 island). The southern most end of the Park lies on the border with Malaysia. Tarutao became Thailand's second marine national park on April 19, 1974. The coastal Khao Sam Roi Yot National Park had been designated in 1966.
The name Tarutao is a Thai corruption of its original Malay name, Pulau Tertua (the island of old).
There are essentially 7 islands of note in the Tarutao/Adang-Rawi archipelagoes:
