Prachaksinlapakhom (th|ประจักษ์ศิลปาคม) is a district (amphoe) in central Udon Thani province, northeastern Thailand.
Neighboring districts are (from the north clockwise) Nong Han, Ku Kaeo, Kumphawapi, and Mueang Udon Thani.
The minor district (king amphoe) was established on 1 June 1997 by splitting it from Kumphawapi district. The creation became effective on 1 July 1997.[1]
