Esher ( EE-shər) is a town in Surrey, England, to the east of the River Mole.
Esher is an outlying suburb of London near the London-Surrey Border, and with Esher Commons at its southern end, the town marks one limit of the Greater London Built-Up Area. Esher has a linear commercial high street and is otherwise suburban in density, with varying elevations, few high rise buildings and very short sections of dual carriageway within the ward itself. Esher covers a large area, between 13 and 15.4 miles southwest of Charing Cross. In the south it is bounded by the A3 Portsmouth Road which is of urban motorway standard and buffered by the Esher Commons.
Esher is bisected by the A307, historically the Portsmouth Road, which for approximately 1 mile (1.6 km) forms its high street. Esher railway station (served by the South West Main Line) connects the town to London Waterloo. Sandown Park Racecourse is in the town near the station.
