This is a list of coats of arms of the United Kingdom, its constituent parts, Crown Dependencies and its Overseas Territories.
The coat of arms of Gibraltar is the oldest in use in an overseas territory of the United Kingdom and is unique in that it dates from before the period of British colonial administration. The version used by the government of Gibraltar are the same as the royal coat of arms of the United Kingdom combined with a badge featuring the own coat of arms of Gibraltar.
Saint Helena, Ascension Island and Tristan da Cunha comprise one British Overseas Territory. There is no flag or coat of arms for the entire territory; each of the constituent parts has its own insignia.
