Tarlo River is a national park located in New South Wales (Australia), 134 kilometres (83 mi) southwest of Sydney.

Proclaimed in 1982, it contains a rugged, unusual landscape not found elsewhere in the region.

Vehicular access is limited to a short stretch of Towrang Road that crosses its southern edge near the locality of Greenwich Park; the rest of the park is surrounded by private properties.

There is an exceptional Aboriginal cultural and historical heritage in this area.
