# List of smallest cities in the United Kingdom

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.
The least populous cities on all of British territory are Jamestown in St Helena, Ascension and Tristan da Cunha (pop. 629) and Hamilton in Bermuda (pop. 854).
