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.
