Elections for Harrow London Borough Council in London were held on 2 May 2002. It was a part of the wider 2002 London local elections. The Conservatives won 50.4% of the vote in the borough. The turnout was 31.5%.
The nominations of sixty Liberal Democrat candidates were rejected by the Returning Officer due to changes brought in by the Registration of Political Parties Act 1998, namely the use of the description "Liberal Democrat Focus Team" when the authorisation certificate issued by their party was for "Liberal Democrats"; this rejection was upheld after a legal challenge. The candidates in the Harrow Weald ward had used "Liberal Democrats" and were not excluded.
