Culgoa National Park, Nature reserve in Brewarrina Shire Council, Australia.

Culgoa National Park covers 35,239 hectares of floodplain along the Culgoa River in north-west New South Wales, with its northern boundary on the Queensland border. River red gums line the watercourse, while coolabah (Eucalyptus coolabah) woodlands cover large sections of the park. The park lies about 660 km north-west of Sydney and 120 km from Brewarrina.

The park was officially established in 1996 to protect floodplain ecosystems that had been altered by colonial pastoral activities. This region has gradually been restored as conservation efforts take place across the landscape.

Aboriginal people lived and worked across this country, many of them as pastoralists on colonial stations, and the park holds the physical remains of that grazing industry. Visitors can still see stock yards, fences and other relics of the pastoral era scattered through the woodland and along the river.

The park is accessible from northern and southern entry points, with a campground near the Culgoa River offering basic facilities. Check conditions before visiting, as water levels and seasonal changes can affect access throughout the year.

Culgoa protects the largest area of coolabah woodland of any national park in New South Wales. The park also shelters the little pied bat (Chalinolobus picatus), a bat found only in Australia, alongside the common brushtail possum. Birdwatchers can look for 10 honeyeater species and six of Australia's woodswallows among the park's more than 150 birds.
