Dorking () is a market town in Surrey in South East England, about 34 km (21 mi) south of London. It is in Mole Valley District and the council headquarters are to the east of the centre. The High Street runs roughly east-west, parallel to the Pipp Brook and along the northern face of an outcrop of Lower Greensand. The town is surrounded on three sides by the Surrey Hills Area of Outstanding Natural Beauty and is close to Box Hill and Leith Hill.
The earliest archaeological evidence of human activity is from the Mesolithic and Neolithic periods, and there are several Bronze Age bowl barrows in the local area. The town may have been the site of a staging post on Stane Street during Roman times, however the name ‘Dorking’ suggests an Anglo-Saxon origin for the modern settlement. A market is thought to have been held at least weekly since early medieval times and was highly regarded for the poultry traded there. The Dorking breed of domestic chicken is named after the town.
The local economy thrived during Tudor times, but declined in the 17th century due to poor infrastructure and competition from neighbouring towns. During the early modern period many inhabitants were nonconformists, including the author, Daniel Defoe, who lived in Dorking as a child. Six of the Mayflower Pilgrims, including William Mullins and his daughter Priscilla, lived in the town before setting sail for the New World.
