# List of national parks of Western Australia

Western Australia, as of 2023, has 112 national parks, of which all but four are named. The oldest of these, John Forrest, was proclaimed in 1900 while the latest, Pimbee and Bunuba, were proclaimed in 2023. The largest number of national parks to be proclaimed was in 2004, when 28 parks were created in the state. Just under 2.6 percent of the state of Western Australia is covered by national parks.
The proposed Helena and Aurora Ranges National Park in the Helena and Aurora Range had its first stage of approval completed in October 2022. Another proposed national park in Western Australia is the Edel Land National Park. Steep Point, the most westerly part of the Australian mainland, would be located within the boundaries of the park.
At the time of the last two-yearly Collaborative Australian Protected Areas Database report in 2022, 6,511,458 hectares (16,090,160 acres) of land in Western Australia was covered by national park, which is 8.55 percent of all protected areas in the state. Overall, just over 30 percent of Western Australia is covered by protected areas.
