Kooyoora State Park, Protected area in Victoria, Australia.

Kooyoora State Park is a protected area in Victoria covering about 11,350 hectares, defined by massive granite outcrops, box-ironbark forests, and native grasslands. The landscape supports many wildlife species, including reptiles and birds adapted to the hilly terrain and rocky habitats throughout the park.

The park was formally established for protection in 1985, but its landscape had earlier significance when it served as a hideout for Captain Melville during Victoria's gold rush in the 1850s. The natural caves that form this refuge remain today as reminders of that era.

The park lies in the country of the Jaara people, who used its rock caves and shelters for protection from the weather. The name Kooyoora is not explained in the sources, and the park's identity is recorded under the alternative forms Kooyoora National Park and Parque nacional Kooyoora. Catto Lodge, the picnic shelter with a stone fireplace and chimney, is named after local resident Stanley Ross Catto, who worked to develop the park.

The park sits about 220 kilometers northwest of Melbourne and offers walking tracks, camping sites, and picnic areas for visitors of different ability levels. The facilities also include Catto Lodge with its stone fireplace, providing a place to rest and enjoy the surroundings.

Melville Caves, formed by massive granite boulders, rise to about 349 meters and offer a natural vantage point across the surrounding land. This rock formation is known for providing historical refuge and today draws walkers seeking elevated viewing spots.
