Campion is an abandoned townsite in the Wheatbelt region of Western Australia, located in the Shire of Nungarin on the Koorda–Bullfinch Road.

[3] A state school was built in Campion in 1925 and opened by the local member of parliament Harry Griffiths, with around 100 people in attendance.

[1] Sir William Campion visited the townsite named in his honour in 1930, in the second-last year of his term as governor.

[1] Following the discovery of alunite on the west side of Lake Campion, a state-owned processing facility was established in 1942 and a new townsite was gazetted at nearby Chandler.

Subsequently development activities focused on Chandler, with the Campion townsite remaining undeveloped and the local school being closed.
