Kwiambal National Park, Nature reserve in Inverell Shire, Australia.

Kwiambal National Park is a national park in north-eastern New South Wales, about 30 km north-west of Ashford. The Severn River joins the Macintyre River below the Macintyre Falls, and granite outcrops stand across the park. The Ashford Caves, limestone caves, lie within its boundaries.

Kwiambal National Park was gazetted on 10 May 2000, covering about 1,301 hectares in County Arrawatta, Parishes Ena, Limestone and Severn. A 2008 vegetation survey by Dr John T. Hunter recorded the park's area as 6,517 hectares.

The name Kwiambal comes from the Indigenous people who lived in this area near the New South Wales-Queensland border. The landscape carries their long connection to this land through its presence today.

The park has several camping areas like Kookibitta and Lemon Tree Flat with basic facilities including toilets and barbecue areas. Visitors should prepare for simple accommodations and be ready for varying conditions depending on the season.

The Ashford Caves, limestone caves within the park, are a feature visitors often miss while heading for the rivers. The park was gazetted on 10 May 2000, and a 2008 vegetation survey by Dr John T. Hunter gave its area as 6,517 hectares.
