Mills Hill railway station is in the Mills Hill area of Middleton in the Metropolitan Borough of Rochdale, in Greater Manchester, England. The station is 5¾ miles (9 km) north of Manchester Victoria on the Caldervale Line. Mills Hill lies on Middleton's common boundary with Chadderton, and thus serves both communities. During the temporary closure of the Oldham Loop line for its conversion to Metrolink light rail (2009–12) the station acted as an informal railhead for much of the borough of Oldham.
