Wolgan Valley is a small valley located along the Wolgan River in the Lithgow Region of New South Wales, Australia. The valley is located approximately 32 kilometres (20 mi) north of Lithgow and 150 kilometres north-west of Sydney.

The name of the Wolgan Valley is derived from “wolga”, a local Australian Aboriginal language name for the climbing plant, Clematis aristata, found in coastal regions of the South-East states of Australia.

The bush walking trails in the area include the Pipeline Track, which goes from Newnes to Glen Davis, and the Wolgan Valley Heritage Trail (see links below), as well as the track from Newnes to the Glowworm Tunnel. There are also camping grounds that are open to the public. The valley also contains numerous slot canyons and is popular for rockclimbing. Commercial tourism came to the valley in 2009 in the form of the Wolgan Valley Resort and Spa. This project was opened by Emirates Groups Hotels and Resorts after examining several sites in Australia.
