Darnhill (or Darn Hill as recorded by the Ordnance Survey) is an area of Heywood, a town within the Metropolitan Borough of Rochdale, in Greater Manchester, England.

Lacking space the Council bought land from neighbouring boroughs to build municipal housing for its bombed out residents.

The Darnhill Estate began construction in the early 1960s with the first family moving in in 1962.

Eventually 5000 people moved to the estate, mainly from the Collyhurst and Miles Platting area of the city In 1998, after consultation with residents, Manchester City Council, transferred its interests in the Darnhill Estate to the Guinness Trust.

Darn Hill is located in the southwestern part of Heywood, between the River Roch (to the north) and East Lancs Railway (to the south).
