Castleton is an area of Rochdale, and an electoral ward of the wider Metropolitan Borough of Rochdale, in Greater Manchester, England. It is 1.2 miles south-southwest of Rochdale town centre and eight miles north-northeast of the city of Manchester.
The most ancient reference to Castleton is found in the Domesday Book of 1086. The name suggest a link with fortification; the Castleton area was the site of Rochdale Castle.
The Rochdale Canal was routed through Castleton around 1800 and made the area one of the larger industrial centres in North West England. The canal granted jobs for hundreds of local residents, and it enabled the construction of several cotton mills.
