Phibunsongkhram Province ({{langx|th|พิบูลสงคราม}}) was a province of Thailand that existed between 1941 and 1946. It was created as a result of the annexation of Cambodian territory by Thailand following the 1940-41 Franco-Thai war. The province was named after Plaek Phibunsongkhram, prime minister of Thailand at the time.[http://www.historytoday.com/george-horvath/thailands-war-vichy-france Thailand's War With Vichy France] The province was dissolved and returned to Cambodia in 1946.
