Hathershaw (or, archaically, Hathershaw Moor) is an urban area of Oldham, in Greater Manchester, England. It occupies a hillside to the immediate south of Oldham town centre, and is bordered by the districts of Coppice and Fitton Hill to, respectively, the north-west and south-east. Hathershaw, which has no formal boundary or extent, is bisected from north to south by the A627 road which leads to Ashton-under-Lyne.
Historically a part of Lancashire, Hathershaw is one of the oldest recorded named places in Oldham, the name occurring in a deed for 1280 with the spelling Halselinechaw Clugh. Existing as a manor house in the 15th century, Hathershaw Hall was the home of a Royalist family in the 17th century who lost part of their possessions as a result of the English Civil War.
