The coronation of James I and his wife Anne as King and Queen of England and Ireland was held on 25 July 1603 at Westminster Abbey. James had reigned as King James VI of Scotland since 1567. Anne was anointed and consecrated with prayers alluding to Esther, the Wise Virgins, and other Biblical heroines. It was the first coronation to be conducted in English instead of Latin. Because of the 1603 London plague, a planned ceremonial Royal Entry to London was deferred until 15 March 1604.

The coronation of the monarch of the United Kingdom is an initiation ceremony in which they are formally invested with regalia and crowned at Westminster Abbey. It corresponds to the coronations that formerly took place in other European monarchies, which have all abandoned coronations in favour of inauguration or enthronement ceremonies. A coronation is a symbolic formality and does not signify the official beginning of the monarch's reign; de jure and de facto their reign commences from the moment of the preceding monarch's death or abdication, maintaining legal continuity of the monarchy.
