This is a list of people who have held the office of Mayor of Harrow. The office was created in 1954 when the Harrow Urban District in Middlesex was incorporated as a municipal borough. Under the London Government Act 1963 Harrow was reconstituted as a London borough with effect from 1 April 1965: a "shadow" council was elected in 1964 and functioned alongside the outgoing borough council. The mayoralty replaced the office of Chairman of Harrow Urban District Council. A list of Chairmen can be seen here.
