Dean Brook is a river near Bolton in Greater Manchester.

Historically within Lancashire, Dean Brook rises on Smithills Moor and flows in an easterly direction, collecting Dakin's Brook at Barrow Bridge and runs through Smithills, before meeting the Raveden Brook to form Astley Brook, which subsequently joins Eagley Brook and forms the River Tonge.
