Wooroloo Regional Park, formerly Chidlow Regional Park, is a conservation park near Chidlow in the Perth Hills, 40 kilometres north-east of Perth, Western Australia, located within the Shire of Mundaring.

Wooroloo, historically also spelled Worrilow and Warriloo, is an Aboriginal word of the Nyungar language, first recorded in 1841.

A Noongar elder who was consulted during the renaming process translated Wooroloo as "come back again" or "you will return".

The purpose of these regional parks is to serve as urban havens to preserve and restore cultural heritage and valuable ecosystems as well as to encourage sustainable nature-based recreation activities.
