Glossop is a market town within the Borough of High Peak in Derbyshire,  England. It lies on the Glossop Brook, a tributary of the River Etherow, about east of the city of Manchester, west of the city of Sheffield and north of the county town of Matlock. Glossop is situated near Derbyshire's county borders with Cheshire, Greater Manchester, South Yorkshire and West Yorkshire. It is between above mean sea level, and uses the tagline "the gateway to the Peak District National Park". Like nearby Buxton, it differs from other areas of the borough in that it is an unparished area, and this distinction defines its boundaries. Glossop is the sixth largest settlement in Derbyshire with a total resident population of 33,020 according to the 2011 census.
