Koh Chang (Thai: เกาะช้าง, pronounced [kɔ̀ʔ tɕʰáːŋ], also Ko Chang) is an amphoe (district) in Trat Province, Thailand. It is on the Gulf of Thailand’s eastern seaboard, 310 km from Bangkok, near the border with Cambodia.
It is the country’s second largest island, after Phuket, and the largest island in the Mu Koh Chang National Park archipelago.
The name means “Elephant Island”, and comes from its elephant-shaped headland. Despite the presence of elephants on the island, they are not indigenous. At present, there are nine villages on the island.
