Epsom and Ewell (/ˈjuːəl, juːl/) is a local government district with borough status in Surrey, England, covering the towns of Epsom and Ewell. The borough lies just outside the administrative boundary of Greater London, but it is entirely within the M25 motorway which encircles London. Many of the borough's urban areas form part of the wider Greater London Built-up Area.

The neighbouring districts are Reigate and Banstead, Mole Valley, Kingston upon Thames and Sutton, the latter two being London boroughs.

Epsom and Ewell lies on the spring line on the north face of the North Downs where pervious chalk meets impervious London clay and a series of springs form. In Ewell the springs which form the Hogsmill River are evident, those in Epsom less so. The springs attracted prehistoric people and remains have been found, mostly in Ewell and particularly near the Hogsmill. In Roman times the road now known as Stane Street, from London to Chichester, passed through Epsom and Ewell. Roman remains have been found in Ewell suggesting a sizeable settlement. Epsom and Ewell have Saxon names: Ewell takes its name from the spring in the centre of the town and Epsom, or Ebbisham, is the enclosure of Ebbi. A Saxon cemetery in The Grove in Ewell was excavated in the 1930s.

In medieval times the area was covered by three manors: Cuddington, which was owned by the Codington family; Epsom, which belonged to Chertsey Abbey; and Ewell, associated with Merton Priory. In 1538 the village of Cuddington was destroyed to make way for Henry VIII's Nonsuch Palace and its parks. Henry died before the palace was complete but it was visited by his daughter Queen Elizabeth. It was demolished in 1682.

Epsom became a spa in the early 17th century when a spring containing Epsom salts was discovered on the Common. Its popularity with London society brought visits from Samuel Pepys and Nell Gwynne, the development of shops and inns and the oldest spa assembly rooms in England. This stands at the western end of Epsom High Street. Horse racing on Epsom Downs began during the spa period, but it was not until the Oaks was run in 1789 and the Derby the following year that it took on its present form. The first grandstand was built in 1830 and Queen's Stand in 1995. The 1927 grandstand was demolished in 2007/8 and the new Duchess's Stand opened in its place in 2009.

Many large houses were built in Epsom during and after the spa period. St Martin's Church was rebuilt in 1825 and partly rebuilt in 1908 and the clock tower in the centre of the town replaced the earlier watchhouse in 1847. Ewell saw less change and, although now surrounded by suburbia. Its medieval church was replaced by the present Victorian one in 1848, but the medieval tower stands in the churchyard.

The Pre-Raphaelite painters, John Everett Millais and William Holman Hunt, had connections with both Ewell and Cuddington and used local scenes as backgrounds for a number of paintings, notably 'Ophelia' by Millais and 'The Light of the World' by Hunt.

In 1937, shortly after the creation of the current district, Epsom and Ewell was granted a coat of arms, which displays the district's link with horse racing and spas. It is: Per chevron vert and argent, in chief two horses heads erased or and in base as many bars wavy azure. The motto is "None Such", a pun on Nonsuch Palace.^[2]

In 1994 and 1995, minor alterations were made to the boundary of Epsom and Ewell with Greater London. This was first to better align the boundary with the Hogsmill River in West Ewell, as well as the roads in Stoneleigh.

Prior to 1995, the border followed the edge of old field boundaries not present since the development of Stoneleigh in the 1930s, causing the border to dissect roads, houses and gardens. There was very little net change in Epsom and Ewell's population.

In 1995 Epsom and Ewell twinned with Chantilly in northern France, another racing town. Links are coordinated by Epsom and Ewell Town Twinning Association.^[3]

Epsom and Ewell Borough Council provides district-level services. County-level services are provided by Surrey County Council.^[15] There are no civil parishes in the borough, which is an unparished area.^[16]
