Morton is a national park in New South Wales, Australia, 170 km southwest of Sydney.
The most notable attractions are the Fitzroy Falls, just off the main road from the Highlands to Kangaroo Valley and Pigeon House Mountain west of Milton. The park consists mostly of a flat plateau dissected by steep gorges, tilting gently to the northeast. It stretches between Bundanoon to the north and west of Ulladulla to the south. It contains part of the Budawang Range and to the south is adjacent to Budawang National Park. To the north, Fitzroy Falls and Belmore Falls plunge off the plateau into rainforest gullies. In the north and northwest of the park, the Shoalhaven River flows. In the east is Mount Tianjara, 768 metres high.
