Nowendoc National Park, Nature reserve in Upper Hunter Shire Council, Australia.

Nowendoc National Park is a nature reserve in the Upper Hunter region featuring eucalypt forests and rainforest across roughly 88 square kilometers. The terrain is hilly and crossed by two year-round creeks that support a variety of plant and animal life.

The New South Wales government established this park in 1999 to protect the natural environment and water resources in the headwaters of the Barnard River. This decision secured the woodland area for future generations.

The park lies on the traditional country of the Ngamba and other Aboriginal groups of the Northern Tablelands, and the German source notes cultural sites in the wider area beyond the campground. The name Nowendoc comes from the nearby town, which the park adjoins on its western edge. Wrights Hut, in the south-eastern section, is a heritage place reached only with a key from the NSW National Parks & Wildlife Service.

All access roads are gravel, winding and steep in places, and unsuitable for caravans. The larger section is reached from Thunderbolts Way north-west of Nowendoc, where Myall Creek campground and Callaghans Canyon lie. The south-eastern section around Wrights Hut needs a 4WD and a key from the NSW National Parks & Wildlife Service for the locked gate south of Nowendoc; both areas are drivable only in dry weather.

The campground by Myall Creek is not named Jacky Barkers in the sources; it is simply the park's basic camping area, with a wood-fired pit barbecue and no other facilities. The south-eastern section around Wrights Hut is reached only with a 4WD and a key from the NSW National Parks & Wildlife Service for the locked gate south of Nowendoc.
