'King's Island') is a Cambodian island located in the Gulf of Thailand, around 1.5 km (1 mi) off the coast of Botum Sakor national park, in the Kiri Sakor district in Koh Kong province, Cambodia.

A fishing community inhabits the island, with people of Khmer, Chinese, Thai and Vietnamese descent.

The bean-shaped island stretches from North to South on a length of around 2.8 km (2 mi), it is rather flat and generally forested.

Natural jungle has been replaced by coconut trees and forest crops for commercial purposes.

As in most of Cambodia, the government is largely nonfunctional even to the extent that the de facto currency is the US DOLLAR.
