Backwell is a village and civil parish in the unitary authority of North Somerset and in 2011 had a population of 4,589. The village lies about 7 miles (11 km) southwest of Bristol, south of the A370 to Weston-super-Mare. The parish includes the hamlets of Backwell Common, Backwell Green, and Backwell Farleigh, and the districts of Backwell West Town and Downside.

Nearby are Nailsea, Flax Bourton, Yatton, Brockley and Barrow Gurney.

Backwell Hillfort between Flax Bourton and Backwell is an Iron Age hill fort.

The village has a long history, appearing in the Domesday Book in 1086 with the name 'Bacoile' meaning 'The well back on the hill'.

The parish was part of the hundred of Hartcliffe.

The lords of the manor from the 12th to 17th centuries were the Rodneys. Walter de Rodney was given the manor for his support of the Empress Matilda against King Stephen.

Backwell House is an historic house in the village which was operated as a boutique hotel between 2016 and 2022.

Backwell has its own parish council, made up of fifteen councillors which have responsibility for local issues, including setting an annual precept (local rate) to cover the council's operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, such as the village hall or community centre, playing fields and playgrounds, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning. Conservation matters (including trees and listed buildings) and environmental issues are also of interest to the council.

The parish falls within the unitary authority of North Somerset which was created in 1996, as established by the Local Government Act 1992. North Somerset Council provides a single tier of local government with responsibility for almost all local government functions within its area, including Backwell. Fire, police and ambulance services are provided jointly with other authorities through the Avon Fire and Rescue Service, Avon and Somerset Constabulary and the South Western Ambulance Service.

North Somerset's area covers the northernmost part of the ceremonial county of Somerset but it is administered independently of the non-metropolitan county. Its administrative headquarters is in the town hall in Weston-super-Mare. Between 1 April 1974 and 1 April 1996, it was in the Woodspring district of the county of Avon. Before 1974 that the parish was part of the Long Ashton Rural District.

An electoral ward in the same name exists. The ward stretches from Brockley, through Backwell to Barrow Gurney in the east and is represented by Bridget Petty of the Green Party of England and Wales since the 2019 council elections. The total population of this ward taken from the 2011 census was 5,930.

Backwell is represented in the House of Commons of the Parliament of the United Kingdom as part of the North Somerset constituency, which was created in 2010 and first used in the 2010 general election. It elects one Member of Parliament (MP) by the first past the post system of election, currently Sadik Al-Hassan, a member of the Labour Party.

Backwell Lake, also known as Buckland's Pool, is, despite its name, much closer to nearby Nailsea. The lake was built as a balancing pond in the mid-1970s and has become a wildlife haven for birds, bats and dragonflies, which are attracted by the open water and surrounding vegetation. Bird species include gadwall, shoveler, pochard, tufted duck, grey heron and mute swans.

On 7 January 2018, local people circled the lake, linking hands, to protest against the proposed building of 700 homes and a four-lane link road in the village by Taylor Wimpey, which they believed would affect the lake and its wildlife.

Stancombe Quarry opened in 1952. Today, the quarry which is operated by Tarmac, produces Carboniferous Limestone, which is mainly for use on the roads, after crushing on site. The site has an expected output of 28 million tonnes over a 25-year period. The now defunct Coles Quarry, in the south of the village, also produced limestone until it was closed by North Somerset Council.

The annual mean temperature is approximately 10 °C (50.0 °F). Seasonal temperature variation is less extreme than most of the United Kingdom because of the adjacent sea temperatures. The summer months of July and August are the warmest with mean daily maxima of approximately 21 °C (69.8 °F). In winter mean minimum temperatures of 1 or 2 °C (33.8 or 35.6 °F) are common. In the summer the Azores high pressure affects the south-west of England, however convective cloud sometimes forms inland, reducing the number of hours of sunshine. Annual sunshine rates are slightly less than the regional average of 1,600 hours. In December 1998 there were 20 days without sun recorded at Yeovilton. Most of the rainfall in the south-west is caused by Atlantic depressions or by convection. Most of the rainfall in autumn and winter is caused by the Atlantic depressions, which is when they are most active. In summer, a large proportion of the rainfall is caused by sun heating the ground leading to convection and to showers and thunderstorms. Average rainfall is around 700 mm (28 in). About 8–15 days of snowfall is typical. November to March have the highest mean wind speeds, and June to August have the lightest winds. The predominant wind direction is from the south-west.

Backwell Playing Fields is a 17-acre (6.9-hectare) public park and a collection of sports fields in the western side of Backwell.

On 6 June 1929 Theodore Robinson opened the park to the public and gave it to the "Children and adults of the parish of Backwell". The fields were opened on 6 June 1929 by the then Marquis of Bath, Thomas Thynne.

As the fields were given to the collective people of Backwell, they had, and continue to have, no sole owner. The fields are, however, managed and maintained by a team of directors of the Backwell Playing Fields Charity.

The fields are often used for playing football, mainly for Ashton and Backwell United FC's home games, as the club's home and stadium is at the Playing Fields. Other sports grounds at the Fields are Backwell Tennis Club, West Backwell Bowling Club, and Backwell Judo Club. The fields are also home to a youth club. 1st Backwell Scouts hut is just outside the park boundaries, but the fields are used a lot by them for their outdoor activities.

Ashton & Backwell United F.C. was originally called Backwell United but then merged with one of Bristol's largest youth club's Ashton Boys FC. They are currently members of the Western League First Division. They moved to their current home in 1947, the Backwell Recreation Ground.
