Mummel Gulf is a national park located in New South Wales, Australia, approximately 487 kilometres (303 mi) by road north of Sydney.

The Mummel Gulf National Park protects tall, open eucalypt forest on the south-eastern escarpment of the New England region.

The explorer John Oxley passed by the Apsley Falls in September 1818 and travelled eastwards through this area en route to Port Macquarie.

The Wool Road (now the Oxley Highway), was built through here in 1842 with convict labour to link the wool-growing settlement of Walcha with Port Macquarie.

Porters (Camp) air navigation facility and Country Energy towers are situated at 1,448 metres (4,751 ft) AHD in the northern portion of the park.
