Broadstone Mill was a double cotton spinning mill on the eastern bank of the Stockport Branch Canal in Reddish, Stockport, Greater Manchester, in England. Construction of the twin mills commenced in 1903 and was completed in 1907. They closed in 1957, and the southern mill and engine houses were demolished in 1965. The northern block went into multiple usage. It is now part of the Houldsworth Village development. It is used as a centre for small businesses, and a shopping outlet.
