Millstream Chichester National Park, Nature reserve in Pilbara region, Western Australia.

Millstream Chichester National Park covers 1,997 km² in the Pilbara, about 150 km south of Roebourne. It combines the old Millstream Station on Millstream Creek, just before it joins the Fortescue River, with the Chichester Range, a rugged range cut by gorges and waterholes. Groundwater-fed pools lined with palms and paperbarks hold water year-round.

Explorer Francis Thomas Gregory named Millstream Creek during his expedition in 1861. The first pastoral lease was granted in 1865, marking the beginning of European pastoral activity in the area.

This land holds deep spiritual meaning for the Yindjibarndi and Ngarluma peoples, with Deep Reach Pool serving as a sacred site in their traditions. The permanent waters and landscape remain central to how these communities connect with their country.

Camping grounds at Miliyanha and Stargazers offer basic facilities for tents and caravans throughout the park. Visitors should bring plenty of water supplies, as the remote desert location requires self-sufficiency.

The homestead that now houses the visitor centre was built in 1920 and served as a tavern between 1975 and 1986. Its rooms hold displays on the Yindjibarndi people, the early settlers and the park's natural environment. The building stands near Millstream Creek, just before it joins the Fortescue River.
