Bueng Boraphet (Thai: บึงบอระเพ็ด, pronounced [bɯ̄ŋ bɔ̄ː.rā.pʰét]) is the largest freshwater swamp and lake in central Thailand. It covers an area of 224 km2 east of Nakhon Sawan, south of the Nan River close to its confluence with the Ping River. This swamp can be seen from the train window between Bueng Boraphet and Thap Krit stations on the Northern railway line.
Originally the area was covered by a large swamp, which was flooded in 1930 with the building of a dam to improve fishing.
Once in the past Siamese tiger perch can be considered the most famous fish species here, until it was said that "If anyone comes to Bueng Borapet and doesn't eat this species of fish it is as if that person has never arrived". But now it is probably completely extinct here, from being caught too much, both for consumption and for trade in the aquarium fish industry.
One hundred and six square kilometres of the lake were declared a non-hunting area in 1975. In 2000 it was designated a wetland of international importance by the Thai government.
