Surrey Archaeological Society is a county archaeological society, founded in 1854 for "the investigation of subjects connected with the history and antiquities of the County of Surrey" in England.
The Society concerns itself with "the County of Surrey within the boundaries existing in 1854 … and as may be enlarged by any extension of the present Administrative County". Its geographical interests therefore cover, in addition to the modern administrative county of Surrey, the areas now forming the London boroughs of Lambeth, Wandsworth, Southwark, Croydon, Kingston, Merton, Sutton, and Richmond; as well as the district of Spelthorne, which became part of the county only in 1965. Where appropriate, however, the Society works in close cooperation with other archaeological agencies, such as Museum of London Archaeology.
The Society’s headquarters, which include an extensive library, are located at Castle Arch, Guildford, which also houses Guildford Museum (itself originally established by the Society, although now quite independent). The Society incorporates nine Special Interest Groups: the Artefacts and Archives Recording Group; the Local History Group; the Medieval Studies Forum; the Prehistoric Group; the Roman Studies Group; the Surrey Industrial History Group; the Villages Study Group; the Guildford Archaeology and Local History Group; and the Research Committee.
The Society's official journal is Surrey Archaeological Collections, first published in 1858, and which now appears annually.
