Nitmiluk National Park is in the Northern Territory of Australia, 244 km southeast of Darwin, and 23 km northeast of the town of Katherine, around a series of gorges on the Katherine River and Edith Falls. Previously named Katherine Gorge National Park, its northern edge borders Kakadu National Park. The gorges and the surrounding landscape have great ceremonial significance to the local Jawoyn people, who are custodians of Nitmiluk National Park.
