The London Metropolitan Archives (LMA) is the principal local government archive repository for the Greater London area, including the City of London: it is the largest county record office in the United Kingdom. It was established under its present name in 1997, having previously been known as the Greater London Record Office. It is administered and financed by the City of London Corporation. The archive is based at 40 Northampton Road, Clerkenwell, London. It attracts over 30,000 visitors a year and deals with a similar number of written enquiries. LMA's extensive holdings amount to over 72 miles of records of local, regional and national importance. With the earliest record dating from 1067, the archive charts the development of the capital into a modern-day major world city. History London Metropolitan Archives in its current form is essentially an amalgamation of four separate bodies.

The County of London was created and controlled by the newly formed London County Council, which took over many of the duties of its predecessor the Metropolitan Board of Works. It was the records of these bodies and similar groups such as the London School Board and Metropolitan Asylums Board that would form the nucleus of the London County Record offices holdings, which were based at County Hall on the south bank of the River Thames. As well as the official records that the council generated, they also began to accept deposits of records fundamental to London's history, such as copies of memorials from the Middlesex Deeds Register, diocesan and parish records and records of charities such as the Foundling Hospital. Under the Public Records Act 1958, the record office became recognised as a place of deposit for public records. Since the
