Milton Keynes is a city in Buckinghamshire, England, about 50 miles (80 km) north-west of London. At the 2021 Census, the population of its urban area was 264,349. The River Great Ouse forms the northern boundary of the urban area; a tributary, the River Ouzel, meanders through its linear parks and balancing lakes. Approximately 25% of the urban area is parkland or woodland and includes two Sites of Special Scientific Interest (SSSIs).

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, seven in Wales, eight in Scotland, 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.
