Chai Nat (Thai: ชัยนาท, pronounced [tɕʰāj nâːt]) is one of the central provinces (changwat) of Thailand.[5] Neighbouring provinces are (from north clockwise) Nakhon Sawan, Sing Buri, Suphan Buri, and Uthai Thani. The town of Chai Nat is 188 km north of Bangkok.[6]


Chai Nat is on the flat river plain of central Thailand's Chao Phraya River valley. In the south of the province the Chao Phraya Dam (formerly Chai Nat Dam) impounds the Chao Phraya River, both for flood control as well as to divert water into the country's largest irrigation system for the irrigation of rice paddies in the lower river valley. The dam, part of the Greater Chao Phraya Project, was finished in 1957 and was the first dam constructed in Thailand. The total forest area is 64 km2 (25 sq mi) or 2.6 percent of provincial area.[7]


Chai Nat was first established during the Ayutthaya period and was used as a successful base of operations for confronting the Burmese army. As the Burmese were defeated every time, the area earned the name Chai Nat, 'place of victory'.[5]

After World War II, when the Japanese had left, economic conditions were bad and food was in short supply. Chai Nat suffered this problem especially badly where bandits grouped up in the countryside stealing cattle and incited violence and crime.[8]


The provincial seal shows a dhammachakka and in the background a mountain. It refers to the Dhammachak Buddha image housed in the hall of Wat Dhammamoen, built on the slope of a mountain.[9]

The provincial tree is the bael fruit tree (Aegle marmelos), and the provincial flower the Rainbow Shower tree (Cassia javanica). Bleeker's sheatfish (Phalacronotus bleekeri) is a provincial fish.

The slogan of the province is "Venerable Luang Pu Suk, renowned Chao Phraya Dam, famous bird park and tasty khao taengkwa pomelo".
