The minor district (king amphoe) Mae Wong was created on 1 April 1992, when the six tambons: Mae Wong, Mae Le, Wang San, Khao Chon Kan, Pang Sawan, and Huai Nam Hom were split off from Lat Yao district. Huai Nam Hom was returned to Lat Yai District on 1 December 1994. On 11 October 1997 the minor district was upgraded to a full district.
