Alexander Morrison National Park is a national park in Western Australia, located 207 kilometres (129 mi) north of Perth in the Shire of Coorow along the Green Head-Coorow Road.

It was named for Alexander Morrison, the first Government Botanist of Western Australia.

The 8,500 hectares (21,004 acres) park contains sandplains and low lateritic breakaways over sandstones and shales of the Lower Jurassic Cockleshell Gully Formation.

Sand heaths are the dominant vegetation, but the park also contains extensive stands of low woodland and mallee typical of the area,[2] especially in the western parts of the park.

[5] The Environmental Protection Authority recommended in 1974 that a one-kilometre-wide strip of vacant Crown land on the south side of Green Head-Coorow Road be added to the reserve[3] – however, this was not actioned.
