This is a list of all mayors and lord mayors of London (leaders of the City of London Corporation, and first citizens of the City of London, from medieval times). Until 1354, the title held was Mayor of London. The dates are those of election to office (Michaelmas Day on 29 September, excepting those years when it fell on the Sabbath) and office is not actually entered until the second week of November. Therefore, the years 'Elected' below do not represent the main calendar year of service.
In 2006 the title Lord Mayor of the City of London was devised, for the most part, to avoid confusion with the office of Mayor of London. However, the legal and commonly used title and style remains Lord Mayor of London.
