Dronfield is a town in North East Derbyshire, England, which includes Dronfield Woodhouse and Coal Aston. It lies in the valley of the River Drone between Chesterfield and Sheffield. The Peak District National Park is three miles (4.8 km) to the west. The name comes from the Old English Dranfleld, probably meaning an open land infested with drone bees.

The town existed before the 1086 Domesday Book, and has a 13th-century parish church. In 1662, Charles II granted the town a market, although this later ceased. The industrial history of the town includes coal mining, the wool trade, the production of soap and steel, and engineering. Today a range of manufacturing firms still operate in the town. The stadium to the north of the town is officially "The Home of Football", providing the playing surface for Sheffield F.C., the world's oldest football club.

Dronfield's population increased in the post-war years from 6,500 in 1945 to 21,261 in the 2011 Census.

Dronfield was in existence before the 1086 Domesday Book, though little is known about its early history. It suffered after the Norman Conquest when William the Conqueror sought to bring the North of England under control. Its name derives from the Old English drān and feld, meaning open land infested with drones (male bees).

The Church of St John the Baptist was built by 1135 when Oscot was rector and the parish of Dronfield covered Little Barlow, Coal Aston, Povey, Holmesfield, Apperknowle, Dore and Totley. The Guild of the Blessed Virgin Mary was established in 1349 in the hall of the chantry priests. However, due to the Dissolution of the Monasteries and the subsequent suppression of the guilds and chantries in 1547, it became a local inn which still operates today as the Green Dragon Inn.

During the 16th century Dronfield with its sheep farmers had a significant number of families working in the wool trade, engaged in spinning and weaving and also the production and selling of cloth. Soaper Lane, being next to the river, was the centre of the soap-making and tanning industry in the town, with a dye works also situated there. In 1662 Dronfield was granted a market by Charles II, but in the 18th century, due to the proximity of Sheffield and Chesterfield, the market went into decline, however it is still held every Thursday in the rear car park of the civic centre on Farwater Lane.

Between the 16th and 19th centuries Dronfield grew around various industries, the most widespread of which was coal mining, with pits at Stubley being mentioned in the 16th century and a map of Hill Top in the 17th century showing some workings. Further mines were opened at Coal Aston in 1785 and Carr Lane in Dronfield Woodhouse in 1795. The town also benefited from trade with the lead mining and grindstone industries in the Peak District. The wealth of the Rotheram family, who became the Lords of the Manor of Dronfield, was based on the lead trade.

The Wilson-Cammell steelworks was built in the town in 1872–3, following the completion of the Midland Main Line through the town in April 1869. Bessemer steel was first blown at the site in March 1873 and the plant was soon capable of producing 700 tons - mostly as rails - every week. Dronfield became a boom town, but its prosperity was short-lived; although more efficient and profitable than other works in the Sheffield area, its site had limitations that could not compete with low-cost coastal locations, and in 1883 production moved from Dronfield to Workington in Cumberland (now Cumbria). Steelworkers and their families moved too. It is estimated that 1,500 townspeople made the trip to Workington. 'Dronnies', as the people of Workington called the newcomers, formed Workington AFC in 1888.
