Keralup is a suburb straddling the southern boundary of the metropolitan area of Perth, Western Australia, on the eastern side of the Kwinana Freeway, and consists entirely of a government strategic landholding.

[2] The suburb's was chosen from a newspaper poll; it was proposed by local Nyoongar leader, Trevor Walley, as it was the name of a pool in the Serpentine River in which he and his friends played as children.

[5] In 1997, plans were announced for the land to be developed into a major satellite city of Perth, with an estimated population of 90,000 people.

The planned development was eventually abandoned in 2015 after the Environmental Protection Authority of Western Australia released a report detailing "disastrous ecological consequences", including the potential for mosquito-borne illnesses deriving from the suburb's position on wetlands to the north of the Peel-Harvey Estuarine System.

[6] In 2018, the state government invited expressions of interest from the private sector for potential uses of the East Keralup site.
