Mount Jerusalem National Park, Nature reserve in New South Wales, Australia.

Mount Jerusalem National Park lies in the Tweed Shire of north-eastern New South Wales, about 40 km north of Lismore and 635 km north of Sydney. It forms the outer rim of the Tweed Caldera, a volcano active 21 million years ago, and three rivers rise within it: the Tweed, Brunswick and Richmond. The Nightcap National Park adjoins it to the south.

Mount Jerusalem National Park was established in 1995 after campaigns against logging in the area, including a blockade in the Nullum State Forest that year. The park lies 635 km north of Sydney and about 40 km north of Lismore, within the Tweed Shire.

The park lies within the Nightcap Range Important Bird Area, identified by BirdLife International because it holds the largest known population of Albert's lyrebirds. The lyrebird's name comes from the male's tail, fanned like a lyre during display; its song mimics other birds and forest sounds. Birdwatchers visit to hear and spot it in the undergrowth.

The park can be entered from several points and offers walking tracks, birdwatching, and outdoor activities for different fitness levels. Bring sturdy shoes and weather-appropriate clothing, as conditions and track difficulty vary across the area.
