Hattah - Kulkyne National Park, Nature reserve in Rural City of Mildura, Australia.

Hattah-Kulkyne National Park covers 48,000 hectares of the Mallee district, known for red dirt and mallee eucalypts, and borders the Murray River. Lake Hattah is the largest of its several lakes, and in the dry season most lakes and their streams dry out completely. Few roads and tracks cross the park, while high-tension power and telegraph lines run through or near it, with large cleared areas around them.

A sanctuary was created at the Hattah lakes in 1915. In 1949 ornithologist Les Chandler and Reverend Clarrie Lang founded the Sunraysia Field Naturalists' Club and campaigned for a national park. The Hattah Lakes National Park was proclaimed on 7 June 1960, and the Kulkyne State Forest was added in 1980 to form the Hattah-Kulkyne National Park.

The park's name comes from the Hattah lakes and the Kulkyne State Forest, added in 1980. In 1949 ornithologist Les Chandler and Reverend Clarrie Lang founded the Sunraysia Field Naturalists' Club, which campaigned for the area's protection. Chandler served as the club's president, vice-president, secretary, treasurer and editor.

The park lies 417 km northwest of Melbourne and 60 km south of Mildura, next to the Murray River. Roads and tracks are few, and high-tension power and telegraph lines cross it, with large cleared areas beneath them. In summer the lakes and their streams dry out completely, so plan around dry lake beds.

The park lies within the Murray-Sunset, Hattah and Annuello Important Bird Area, identified by BirdLife International for its mallee habitat, which supports threatened species such as the malleefowl, black-eared miner and mallee emu-wren. Over 200 bird species have been recorded in the park.
