The London Borough of Richmond upon Thames (pronunciation) in southwest London, England, forms part of Outer London and is the only London borough on both sides of the River Thames. It was created in 1965 when three smaller council areas amalgamated under the London Government Act 1963. It is governed by Richmond upon Thames London Borough Council. The population is 198,019 and the major communities are Barnes, East Sheen, Mortlake, Kew, Richmond, Twickenham, Teddington and Hampton.

The borough is home to Richmond Park, the largest park in London, along with the National Physical Laboratory and The National Archives. The attractions of Kew Gardens, Hampton Court Palace, Twickenham Stadium and the WWT London Wetlands Centre are within its boundaries and draw domestic and international tourism. In 2023, the borough was ranked first in Rightmove's Happy at Home index, making it the "happiest place to live in Great Britain"; the first time a London borough has taken the top spot.

There had been a borough called Richmond since 1890 when the Municipal Borough of Richmond was created. It was enlarged in 1892 to include Kew, Petersham and North Sheen, and again in 1933 to include Ham.

The larger London Borough of Richmond upon Thames was created in 1965 under the London Government Act 1963, covering the combined area of the former borough of Richmond plus the neighbouring Municipal Borough of Barnes and the Municipal Borough of Twickenham. Barnes and Richmond had both been in Surrey prior to the reforms, whilst Twickenham had been in Middlesex. The area was transferred to Greater London to become one of the 32 London boroughs. The new borough was named 'Richmond upon Thames' rather than just Richmond as the old borough had been called; it is the only London borough to straddle the River Thames.

Minor boundary changes have occurred since its creation. The most significant amendments were made in 1994 and 1995, when areas of Richmond Park were transferred from the London Borough of Wandsworth and the Royal Borough of Kingston upon Thames.

The borough is approximately half parkland, with notable parks including Richmond Park, Bushy Park, Kew Gardens, Old Deer Park and Hampton Court Park. There are over 100 parks and open spaces in the borough and 21 miles (34 km) of river frontage. 140 hectares within the borough are designated as part of the Metropolitan Green Belt.

The predominant other land use is residential. Most businesses within the borough consist of retail, property improvement/development and professional services. Parts of the borough, including Barnes, Richmond, St Margarets, Cambridge Park and Marble Hill, some areas of Twickenham and much of East Sheen rival Stanmore Hill and Kenley as the highest house-price districts and neighbourhoods in Outer London.

The borough is home to the National Physical Laboratory and the attractions of Hampton Court Palace, Twickenham Stadium and the WWT London Wetlands Centre that draw domestic and international tourism.

The River Thames becomes narrower than at any part of Inner London towards its flow into the borough and becomes non-tidal at Teddington Lock in the borough; its main axis runs south to north, rather than west to east through more than half of the borough.

London's German business and expatriate community is centred on this borough, which houses the German School London (DSL) and most of the capital's German expatriates.

The local authority divides the borough into fourteen loosely bounded neighbourhoods, or "villages". Some of the neighbourhoods have the same name as their associated political ward, but the boundaries are not officially aligned. There is also no direct alignment between these areas and postcode districts, which tend to cover much broader areas, crossing the borough boundaries. There are four post towns based in the borough: Hampton, Richmond, Teddington and Twickenham. Parts of the borough come under the London post town, including Barnes and Mortlake, and there are several other peripheral parts of post towns based in neighbouring boroughs which straddle the administrative boundary. Although most addresses in the borough have TW postcodes, some have SW and KT postcodes.

The council meets at York House in Twickenham and has its main offices at the adjoining Civic Centre at 44 York Street.

Since 2000, for elections to the London Assembly, the borough forms part of the South West constituency, currently represented by the AM Gareth Roberts.

The borough is split between three constituencies. The entire portion of the borough south of the River Thames is included in the Richmond Park constituency, which also contains some of the northern wards of the borough of Kingston.

Most of the portion of the borough north of the river forms the constituency of Twickenham, which does not contain wards from any other borough. However, since the 2024 general election, the borough's northernmost ward on this side of the Thames, Whitton, has instead been included in the constituency of Brentford and Isleworth, the remainder of which consists of wards from the London Borough of Hounslow.

Prior to the 2024 election, the entirety of the borough north of the Thames had formed the entirety of the Twickenham constituency since 1997.

In 2006, research commissioned by a major mortgage lender found that, on the quantitative statistical indices used, the borough had the best quality of life in London and was in the top quarter of local authorities nationwide. A neighbouring authority in Surrey achieved the best quality of life in that report.

Richmond is one of London's wealthiest boroughs on many measures. It has the lowest rates of poverty, child poverty, low pay, child obesity and adults without level 3 qualifications of any London borough, according to a 2017 research project by Trust for London.

Demography is a diverse picture as in all of London: each district should be looked at separately and even those do not reflect all neighbourhoods. Whatever generalisations are used, "the fine-grained texture of London poverty" by its minutely localised geography must always be taken into account according to an influential poverty report of 2010. Richmond upon Thames has the lowest child poverty rates in London at 20% and contains at least one ward with an above-average level (for London) of working-age adults receiving out-of-work benefits but even this borough – reflecting the best result – has two standard poverty indices of sixteen in which it is placed in the worst quarter of boroughs.

Note:

The borough's history is reflected in the coat of arms, which was officially granted on 7 May 1966. It is: Ermine a portcullis or within a bordure gules charged with eight fleurs-de-lis or. The crest is: On a wreath argent and gules out of a mural crown gules a swan rousant argent in beak a branch of climbing red roses leaved and entwined about the neck proper.

The portcullis was taken from the arms of the Municipal Borough of Richmond; the swan crest, from the arms of the Municipal Borough of Twickenham; and the griffin supporters and shield from the arms of the Municipal Borough of Barnes. Red, gold and ermine are the royal livery colours, reflecting Richmond's royal history. The swan represents the River Thames, which flows through the borough. The oars are from the Oxford University Boat Club and the Cambridge University Boat Club, reflecting the fact that the Boat Race between the two universities ends at Mortlake in the borough.

Richmond upon Thames is the local education authority for the borough.

Richmond upon Thames College opened in 1977 and was the first tertiary college in Greater London. The borough adopted a tertiary post-16 provision with virtually all 16-19 studies taking place at this college. This system lasted until 2012 when the council approved the creation of sixth forms in schools. Additionally the council approved the creation of a Catholic secondary school for the first time in the borough.

Richmond's swimming pools, Pools on the Park, are located in Old Deer Park close to the town centre. The outdoor pool is open in the summer months only. There is also a heated outdoor pool in Hampton.

The Twickenham Museum is a volunteer-run museum opposite St Mary's parish church.

The Museum of Richmond, in Richmond's Old Town Hall, close to Richmond Bridge, has displays relating to the history of Richmond, Ham, Petersham and Kew. Its rotating exhibitions, education activities and a programme of events cover the whole of the modern borough. The museum's highlights include 16th-century glass from Richmond Palace and a painting, The Terrace and View from Richmond Hill, Surrey by Dutch draughtsman and painter Leonard Knyff (1650–1722), which is part of the Richmond upon Thames Borough Art Collection.

The gallery is also the site of the London Borough of Richmond upon Thames' arts service and provides educational workshops for a wide variety of ages, using the converted stables and coach house as educational spaces.

Garrick's Temple to Shakespeare in Hampton hosts a free Sunday afternoon Shakespeare exhibition from April to October and a series of summer drama, music and exhibitions.

Richmond has two theatres. The Richmond Theatre at the side of Little Green is a Victorian structure designed by Frank Matcham and restored and extended by Carl Toms in 1990. The theatre has a weekly schedule of plays and musicals, usually given by professional touring companies, and pre-West End shows can sometimes be seen. There is a Christmas and New Year pantomime tradition and many of Britain's greatest music hall and pantomime performers have appeared here.

Close to Richmond railway station is the Orange Tree Theatre which was founded in 1971 in a room above the Orange Tree pub. As audience numbers increased there was pressure to find a more accommodating space and, in 1991, the company moved to current premises within a converted primary school. The 172-seat theatre was built specifically as a theatre in the round. It has acquired a national reputation for the quality of its work for staging new plays, and for discovering undeservedly forgotten old plays and neglected classics.
