Chum Saeng is an old district of Nakhon Sawan. The government separated some parts of Mueang Nakhon Sawan District to establish Tambon Koei Chai. In 1903, the Interior ministry upgraded the tambon to be Phan Lan District, named after the central tambon. A few years later, the name was changed back to Koei Chai. The district office was moved to the west bank of the Nan River and renamed to Chum Saeng in 1915.
