About the Middlesex flag

The flag of Middlesex is the flag of the English county of Middlesex. This is the traditional flag of Middlesex, the county that forms the central and north-west parts of Greater London. This traditional design is included in the Flag Institute's registry of local flags as the Middlesex Flag.

The flag is a banner of the arms of the former Middlesex County Council, abolished in 1965. Whilst such banners of county arms are legally not generally available for public use, a similar design had been used traditionally as a local badge in Middlesex and neighbouring Essex for centuries.
