Tooloom National Park, Nature reserve in Northern Rivers region, New South Wales, Australia.

Tooloom National Park is a nature reserve containing 4,380 hectares of subtropical rainforest in the Northern Rivers region of New South Wales. The landscape features giant white beech trees, thorny yellowwoods, and dense vegetation patterns that define the terrain.

Tooloom National Park lies within the Focal Peak Group of the Gondwana Rainforests of Australia, inscribed as a World Heritage Site in 1986 and added to the Australian National Heritage List in 2007. The Githabul Aboriginal people once lived in the area, and a land agreement allowed the land to be used as a national park; the Githabul now take part in its management.

The name Tooloom comes from the Bundjalung word Duluhm, meaning headlice, a reference to Tooloom Falls. The Githabul Aboriginal people once lived in the area, and a land agreement allowed the land to be used as a national park; the Githabul now take part in managing it.

The park has walking tracks, picnic areas with tables, and barbecue facilities available year-round except during severe weather. Visit during drier periods to safely use the trails and facilities.

Ten different species of kangaroos and wallabies live in the park, including the endangered long-nosed potoroo sheltering in dense undergrowth. These rare animals are difficult to spot, but their presence signals an intact ecosystem.
