The South Para River is a river in Australia. It rises in the Mount Lofty Ranges near Mount Crawford and Kersbrook and flows northwest through the Mount Lofty Ranges, passing through the Warren Reservoir and the South Para Reservoir, before merging with the North Para River in Gawler forming the Gawler River.
The South Para River catchment is one of the key watersheds in the northern Mount Lofty Ranges. It plays an important role in the functioning of South Australia, providing much of the water used by Adelaide's domestic supply in the Northern Adelaide area. The rainfall in the South Para River catchment varies from 775 mm per annum in the north-east of the catchment to 675 mm per annum near Williamstown. Its waters are also used for livestock production, cereal cropping and recreation.
