Koh Kut is a district (Amphoe) of Trat Province, eastern Thailand, consisting of a group of islands. With a population of about 2000 it is the district with the lowest population of all Thailand.
Originally the area of the district was part of the subdistrict (tambon) Koh Chang, Laem Ngop district. In 1952 the subdistrict Koh Mak was established covering the whole island, at that time subdivided into 4 villages (muban). In 1980 three villages of Koh Mak were split off to create the subdistrict Koh Kut. On April 1, 1990 the government upgraded tambon Koh Kut together with tambon Koh Mak to a minor district (King Amphoe).
Following a decision of the Thai government on May 15, 2007, all of the 81 minor districts were to be upgraded to full districts.With the publishing in the Royal Gazette on August 24 the upgrade became official.
As local government entities the two Tambon administrative organizations (TAO) were created in 2003 and 2004 respectively. The Tambon Council Koh Kut was upgraded to a TAO in 2003, and for Koh Mak in 2004.
It is a major island ringed by sleepy seaside villages and coconut plantations. It is about 60 minutes from the mainland by speedboat.
Kut Island has limited infrastructure and hence is not as popular as nearby Koh Chang. Several resorts on the islands cater to tourists who prefer a quiet and family-friendly atmosphere. The island has great beaches and is a great spot to get away from the “farang crowd”(tourists).
