Acacia Hills is an outer rural locality of Darwin. It is 60 kilometres (37 mi) south of the Darwin CBD.
The local government area that it is a pert of is the Litchfield Municipality. The suburb is mostly a rural area, just north of Adelaide River. The Stuart Highway runs through Acacia Hills and the suburb's name comes from the acacia shrub that is endemic in the area.
The area was the site of the 1999 Acacia Hills Shootout, where bushman Rodney Ansell ambushed several policemen at a roadblock. Ansell killed one policeman but was eventually shot himself in the gun battle that followed.
