The Cheesden Valley is a valley in the Heywood area of Greater Manchester, England. It runs on a north-south alignment between Bury and Rochdale in the Metropolitan Borough of Rochdale. Cheesden Brook runs through the valley, joining with Naden Brook to eventually run into the River Roch near Heywood. During the industrial age the valley became a centre of cotton production dependent on running water. The valley is now a conservation area.
