Leatherhead is a town in the Mole Valley district of Surrey, England, about 17 mi (27 km) south of Central London. The settlement grew up beside a ford on the River Mole, from which its name is thought to derive. During the late Anglo-Saxon period, Leatherhead was a royal vill and is first mentioned in the will of Alfred the Great in 880 AD. The first bridge across the Mole may have been constructed in around 1200 and this may have coincided with the expansion of the town and the enlargement of the parish church.

Mole Valley is a local government district in Surrey, England. Its council is based in Dorking, and the district's other town is Leatherhead. The largest villages are Ashtead, Fetcham and Great Bookham, in the northern third of the district.
