Katherine South Primary School is situated on Riverbank Drive in the town of Katherine, in the Northern Territory of Australia.
The school was opened in 1976 in makeshift accommodation at the Katherine Showgrounds. Demount-able classrooms were provided in the middle of that year on the southern side of the oval while building went ahead on the present site. The late Les Macfarlane, then Member for Elsey, officially opened the permanent school buildings on 14 September 1979.
