History.
The district was created in 1827 and called "khwaeng" Kaeng Khoi. The district office was in Ban Tan Diao. In 1897, the "khwaeng" was converted to an "amphoe". The office of the district was moved from the Pa Sak River bank to the nearby Kaeng Khoi Railway Station in 1915. 
Its name "Kaeng Khoi" distorted from "Raeng Khoi" (แร้งคอย), directly translated as 'vulture waiting'. Because the district in the past was the gateway to "Dong Phaya Fai" (ดงพญาไฟ) or presently Dong Phaya Yen. The large rain forest was full of wildlife and malaria. Many people died while traveling here, so often the vultures gathered to wait to eat the corpses.
