The Kororoit Creek is a watercourse of the Port Phillip catchment, rising in the outer north western suburbs of Melbourne, in the Australian state of Victoria.

The traditional custodians of the land surrounding the creek are the Wurundjeri people who had hunted, fished mulloway and tiger sharks in rare occasions.
