Anlong Veng is a district (srok) located in the Oddar Meanchey province of Cambodia. The primary town within this district shares the same name, Anlong Veng.
The area is historically significant due to its association with the Khmer Rouge. It is estimated that approximately 35% of the district's population consisted of former Khmer Rouge soldiers, including the movement's leader and dictator, Saloth Sâr. Due to ongoing conflict at the time of the 1998 census, an official population count for the district could not be recorded.
