Cape Hillsborough National Park, Nature reserve in Mackay Region, Australia.

Cape Hillsborough National Park covers a volcanic peninsula largely under rainforest, rising to 267 m, about 40 km northwest of Mackay in the O'Connell River catchment. The cape at its tip was named by Lieutenant James Cook in 1770 after Wills Hill, Earl of Hillsborough. The park was enlarged by 204 hectares on National Parks Day, 28 March 2010.

Lieutenant James Cook named the cape at the peninsula's tip in 1770, honouring Wills Hill, Earl of Hillsborough, then President of the Board of Trade and Plantations. On National Parks Day, 28 March 2010, the Queensland government added 204 hectares to the park, bringing it to just over eleven square kilometres.

The name Cape Hillsborough was given by Lieutenant James Cook in 1770, honouring Wills Hill, Earl of Hillsborough, then President of the Board of Trade and Plantations. Visitors today see the cape's volcanic headland and rainforest, and at low tide sand bubbler crabs leave patterns drawn in the sand.

The park is well-served by marked walking trails that pass through different landscapes. Camping areas with basic facilities are available, and information boards about local wildlife are posted throughout the reserve.

At dawn, eastern grey kangaroos and wallabies gather on the beach to feed on mangrove seed pods and seaweed. This daily wildlife event is most visible to visitors who arrive at sunrise.
