Wialki is a townsite in the eastern Wheatbelt region of Western Australia.

It is situated between Beacon and Bonnie Rock, in the shires of Mount Marshall and Mukinbudin.

Wialki was originally a siding on the Burakin to Bonnie Rock railway extension planned to pass through the area in 1929; the district surveyor suggested the station should be named Datjoin but the Railway department chose the name Wialki after the Aboriginal name of a nearby soak.

[2] The surrounding areas produce wheat and other cereal crops.
