The flag of Greater London consists of a red vertical stripe with a gold Saxon crown on top and 6 wavy stripes of blue and white on the bottom. It was used as the heraldic banner of the Greater London Council from 1965-1986.

In February 2020, the London Assembly, part of the Greater London Authority, unanimously supported a motion by Tom Copley to have the Greater London Council's coat of arms transferred to the authority. In November 2024, the assembly confirmed its support for the transfer of the arms, and in January 2025, Sadiq Khan, the mayor of London, approved the submission of a petition to King Charles III via the College of Arms. The request was granted on 13 November 2025, with both the arms and badge of the Greater London Council being transferred to the Greater London Authority.
