Dong Mueang Aem was a group of ancient settlements located in Dong Mueang Aem subdistrict, Khao Suan Kwang, Khon Kaen, northeastern Thailand, controlling trade route between the Songkhram River basin to the north and the Chi–Mun basins to the south. It was inhabited from the 6th – 18th centuries from the Dvaravati to the late Ayutthaya periods, and was once being sacked by Mahendravarman of Chenla during his expansion campaign to the Chi-Mun Valley. After being abandoned for a century, it was repopulated by Lao people in 1859.
