In the past, Nang Buat District covered a large area. Prince Damrong Rajanubhab and the governor of Suphan Buri agreed to separate the northernmost part and then created a new district named Doem Bang on 16 May 1911. Two tambons of Hankha District, Chai Nat Province and two tambons of Bang Rachan District, Sing Buri Province were added. In 1939 the government changed the district name of Nang Buat District to Sam Chuk, they decided to put the word Nang Buat after Doem Bang, so since that year the district is named Doem Bang Nang Buat. Its name literally means 'formerly place of ordained lady', according to folklore from the Sukhothai period.
