The Kui Buri National Park ( Thai: อุทยานแห่งชาติ กุยบุรี ) is a national park in Thailand. It is located in Tenasserim mountain range in the province of Prachuap Khiri Khan. To the north it borders on the Kaeng Krachan National Park.
The National Park is home to about 250 wild Asian elephants and over 150 Gaure. This graze together with Banteng cattle on the open savannah grasslands of the park. More endangered large animals that find a refuge in the park, are Indochinese Tiger, Clouded Leopard, Asiatic black bears, jackals gold, sun bears and tapirs. In the 1990s, there were frequent conflicts between farmers and wildlife. At the behest of King Bhumibol Adulyadej dams were built outside the park, which the farmers allowed to irrigate fields there. Then laid many farmers their fields from the park area which the wild animals gave more space in the border areas. The stocks of wild animals rise in the meantime. Poaching could be restricted through the use of rangers.
