Dinckley Brook is a minor river of Lancashire, England. The stream rises at the confluence of several minor watercourses at Wheatley Farm close to Copster Green and flows northwards, through Cunliffe House Wood and under Dinckley Bridge (near to where it meets Park Brook). The brook continues past Brockhall, Great Wood and Bradyll, continuing past the Brockhall training base of Blackburn Rovers and through Mill Wood.
