List of cities in the United Kingdom in the context of "Lord Mayor"

Edinburgh is the capital city of Scotland and one of its 32 council areas. It is located in southeast Scotland and is bounded to the north by the Firth of Forth and to the south by the Pentland Hills. Edinburgh had a population of506,520 in 2020, making it the second-most-populous city in Scotland and the seventh-most-populous in the United Kingdom. The wider metropolitan area had a population of 912,490 in the same year.

Recognised as the capital of Scotland since at least the 15th century, Edinburgh is the seat of the Scottish Government, the Scottish Parliament, the highest courts in Scotland, and the Palace of Holyroodhouse, the official residence of the British monarch in Scotland. It is also the annual venue of the General Assembly of the Church of Scotland. The city has long been a centre of education, particularly in the fields of medicine, Scottish law, literature, philosophy, the sciences and engineering. The University of Edinburgh was founded in 1582 and is now one of three universities in the city. The financial centre of Scotland, Edinburgh was in 2020 ranked the second-largest financial centre in the United Kingdom, the fourth-largest in Europe, and the thirteenth-largest in the world in the Global Financial Centres Index.

Cardiff (/ˈkɑːrdɪf/ ; Welsh: Caerdydd [kairˈdiːð, kaːɨrˈdɨːð] ) is the capital and largest city of Wales. Cardiff had a population of 383,919 in 2024 and forms a principal area officially known as the City and County of Cardiff (Welsh: Dinas a Sir Caerdydd). The city is the eleventh largest in the United Kingdom. Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. The Cardiff urban area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth.

Cardiff is the main commercial centre of Wales as well as the base for the Senedd, the Welsh Parliament. At the 2021 census, the unitary authority area population was put at 362,400. The population of the wider urban area in 2011 was 479,000. In 2011, it ranked sixth in the world in a National Geographic magazine list of alternative tourist destinations. It is the most popular destination in Wales with 21.3 million visitors in 2017. It was voted as the best city in the UK at the 2023 Readers' Choice Awards.

Glasgow is the most populous city in Scotland, located on the banks of the River Clyde in west central Scotland. It is the fourth-most populous city in the United Kingdom and the 27th-most populous city in Europe, and comprises 23 wards which represent the areas of the city within Glasgow City Council. Glasgow is a leading city in Scotland for finance, shopping, industry, culture and fashion, and was commonly referred to as the "second city of the British Empire" for much of the Victorian and Edwardian eras.

In 2020, it had an estimated population as a defined locality of 632,350. More than 1,000,000 people live in the Greater Glasgow contiguous urban area, while the wider Glasgow City Region is home to more than 1,800,000 people (its defined functional urban area total was almost the same in 2020), around a third of Scotland's population. The city has a population density of 3,562 people per km, much higher than the average of 70/km for Scotland as a whole. Glasgow grew from a small rural settlement close to Glasgow Cathedral and descending to the River Clyde to become the largest seaport in Scotland, and the tenth-largest by tonnage in Britain. Expanding from the medieval bishopric and episcopal burgh (subsequently royal burgh), and the later establishment of the University of Glasgow in the 15th century, it became a major centre of the Scottish Enlightenment in the 18th century.

City status in the United Kingdom is granted by the monarch of the United Kingdom to specific centres of population, which might or might not meet the generally accepted definition of cities. As of 22 November 2022, there are 76 cities in the United Kingdom—55 in England, eight in Scotland, seven in Wales and six in Northern Ireland. Although it carries no special rights, the status of city can be a marker of prestige and confer local pride.

The status does not apply automatically on the basis of any particular criteria, though until 1889 in England and Wales it was limited to towns with diocesan cathedrals. This association between having an Anglican cathedral and being called a city was established in the early 1540s when King Henry VIII founded dioceses (each having a cathedral in the see city) in six English towns and granted them city status by issuing letters patent. A city with a cathedral is often termed a cathedral city.

The table displays the 31 smallest of the cities in the United Kingdom across three measures. Most of these appear in all three of the following categories:

• Area (body): This default sort ranks the physically smallest 23 local government areas (parish/community, district, county) and if missing, a built-up locality that has city status
• Area (locale): 24 cities with the smallest same-name built-up area (many cities have much countryside and multiple settlements within their boundaries)
• Census population: 24 cities around 100,000 residents and fewer since the 2001 census

Lichfield, Hereford and Salisbury, in addition to being some of the smallest cities in England, are among the most populous civil parishes.

Cambridge (/ˈkeɪmbrɪdʒ/ KAYM-brij) is a city and non-metropolitan district in the county of Cambridgeshire, England. It is the county town of Cambridgeshire and is located on the River Cam, 55 miles (89 km) north of London. As of the 2021 United Kingdom census, the population of the City of Cambridge was 145,700; the population of the wider built-up area (which extends outside the city council area) was 181,137. There is archaeological evidence of settlement in the area as early as the Bronze Age, and Cambridge became an important trading centre during the Roman and Viking eras. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951.

The city is well known as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world. The city's skyline is dominated by several college buildings, along with the spire of the Our Lady and the English Martyrs Church, and the chimney of Addenbrooke's Hospital.
