Now on the edge of Stockport in Greater Manchester, Mellor's location is historically important. 

On the south-west and north-west, it is bordered by the two great rivers, Goyt and Etherow, which drain the SW Peak District and join to form the Mersey at the lowest point of Mellor.

On the east, a high ridge overlooks a valley, behind which is Kinder Scout. Three spurs, separated by brooks, project west from the ridge.
