Mu Ko Chang National Park is a marine national park in Ko Chang District, Trat Province, eastern Thailand, covering 650 square kilometers and 52 islands in the Gulf of Thailand. Established in 1982, it encompasses Ko Chang, Ko Kut, Ko Mak and smaller islands, featuring rainforested mountains, waterfalls, white-sand beaches and coral reefs. It is notable for its island-hopping, snorkeling, diving and hiking opportunities within a protected archipelago near the Cambodian border.

Visitors can expect a large archipelago with forested interior mountains, waterfalls such as Khlong Phlu and Than Mayom, white-sand beaches and clear waters with coral reefs. The park is explored via hiking trails, viewpoints, beaches and boat trips between islands. Facilities are centered at the park headquarters and waterfall entrances, while most islands are reached by ferry, speedboat or kayak for swimming, snorkeling, diving and sightseeing.

Established on 31 December 1982 as Thailand's 45th national park, covering approximately 650 square kilometers of land and sea in the Gulf of Thailand to protect the Ko Chang archipelago's forests, beaches and marine ecosystems.

The archipelago supports traditional fishing communities and coastal villages such as Bang Bao, with local livelihoods linked to fishing and tourism within the protected marine landscape.
