Millstream Chichester National Park is a national park in the Pilbara region of Western Australia (Australia), and is located 1,190 kilometres (739 mi) north of the state capital, Perth. The park is made up of the old Millstream station which is on the Millstream Creek, just before it joins Fortescue River one of the few permanent watercourses in the area and the Chichester Range.
The area is homeland of the Yinjibarndi people. Millstream Creek was named by the explorer Francis Thomas Gregory in 1861. He reported the favourable grazing prospects. The first pastoral lease was taken up on 1865. The present Millstream Homestead was built in 1920. The homestead was a tavern between 1975 and 1986.
