Eastern Thailand is a region of Thailand bordering Cambodia on the east, Northeastern Thailand in the north, and central Thailand on the west.


Eastern Thailand lies between the Sankamphaeng Range, which forms a natural border with the Khorat Plateau to the north and the Gulf of Thailand to the south. The geography of the region is characterised by short mountain ranges (collectively grouped under the Chanthaburi Range) alternating with small basins of short rivers which drain into the Gulf of Thailand. Between the Chanthaburi and Sankamphaeng mountains lies the basin of the Bang Pakong River system.

Fruit is a major component of agriculture in the area, and tourism plays a strong part in the economy. The region's coastal location has helped promote eastern seaboard industrial development, a major factor in the economy of the region.[3]

Islands off Eastern Thailand's coast include Ko Sichang, Ko Lan, Ko Samet, and Ko Chang.

National parks

Within the eastern region there are some eight national parks. Pang Sida National Park covering 844 km2 in Sa Kaeo province, it constitutes a part of the Dong Phayayen-Khao Yai Forest Complex UNESCO World Heritage Site, covering in total around 6,100 km2. The total forest area is 8,205 km2 (3,168 sq mi) or 22.4 percent of this eastern region area (incl. Nakhon Nayok province).[1] Mu Ko Chang National Park in Trat province includes 85 per cent of Thailands second largest island Ko Chang. The beaches on the western coast of Ko Chang have been excluded from the national park for reason of facilitating the tourism industry. Mu Ko Samet National Park in Rayong province is just 6 km long by 3 km wide with beaches covered with some of the finest white sand in the country.

According to the six geographical regions established by the National Research Council of Thailand, the eastern region includes seven provinces.
