Holmfirth is a town in the Metropolitan Borough of Kirklees, West Yorkshire, England, on the A635 and A6024 in the Holme Valley, at the confluence of the River Holme and Ribble, 6 miles (9.7 km) south of Huddersfield and 14 miles (23 km) west of Barnsley. It mostly consists of stone-built cottages nestled in the Pennine hills. The boundary of the Peak District National Park is 2 miles (3.2 km) south-west of the town.

Historically part of the West Riding of Yorkshire, Holmfirth was a centre for pioneering film-making by Bamforth & Co., which later switched to the production of saucy seaside postcards. Between 1973 and 2010, Holmfirth and the Holme Valley became well known as the filming location of the BBC’s situation comedy Last of the Summer Wine.
