Karijini National Park is an Australian national park centred in the Hamersley Ranges of the Pilbara region in the northwestern section of Western Australia. The park is located north of the Tropic of Capricorn, 1,055 kilometres (656 mi) from the state's capital city, Perth. Formerly known as Hamersley Range National Park, the park was officially renamed in 1991.
At 627,422 hectares (1,550,390 acres), Karijini is the second largest national park in Western Australia (behind Karlamilyi National Park).
The park is physically split into a northern and a southern half by a corridor containing the Hamersley & Robe River railway and the Marandoo iron ore mine.
The park is served by the Solomon Airport, located 15 kilometres (9.3 mi) to the west.
