The Western Australian Naturalist (also known as The Naturalist), is the peer-reviewed scientific journal of the Western Australian Naturalists' Club. It publishes original research on topics related to the natural history of Western Australia.
It was established in 1947.
Similar publications emanated from groups that were established in other Australian states, the South Australian being a part of the Royal Society in that state and the Victorian publication was established as early as the 1880s.
The editor from 1947 to 1980 was Dom Serventy.
At times the publication and contents of the issues of The Naturalist were noted in the local newspaper the The West Australian.
The history of the club was first published in The Naturalist in 1964 and subsequently expanded and published separately at a later date.
George Seddon in his work Sense of Place wrote: "there are three good local inexpensive journals that should be in every school and public library The Journal of the Royal Society of Western Australia, the Journal and Proceedings of the Royal Western Australian Historical Society and The Western Australian Naturalist".
