Breakfast Creek, an urban watercourse[1] that is part of the Hawkesbury-Nepean catchment, is located in Greater Western Sydney, New South Wales, Australia.

Breakfast Creek is severely modified and has few significant natural values with regard to habitat and longitudinal connectivity.

Breakfast Creek attributes include community usage and access, such as the Ashlar Golf Course.

The cycle paths and proximity to sports facilities and schools throughout much of the creek have led to one of the most accessible watercourses within Blacktown.

[3] Breakfast Creek is transversed by the Westlink M7 and the Richmond railway line at Quakers Hill.
