Keighley is a town and civil parish within the metropolitan borough of the City of Bradford in West Yorkshire, England. Historically in the West Riding of Yorkshire, it is situated northwest of Bradford and is at the confluence of the rivers Aire and the Worth. The town area, which is part of the Brontë Country, has a population of 89,870, making it the third largest civil parish in England.
Keighley lies in a fold between the countryside of Airedale and Keighley Moors. The town is the terminus of the Keighley and Worth Valley Railway, a heritage steam branch line which has been restored and runs through the Worth Valley to Oxenhope via Oakworth and Haworth.
Prior to 1974 when West Yorkshire replaced this part of the West Riding of Yorkshire, Keighley was a municipal borough.
