Tyne and Wear Archives Service (TWAS) is the record office for the metropolitan county of Tyne and Wear, in North East England. TWAS preserves documents relating to the area from the 12th to the 21st century and provides free access to them for all.
The Archives Service was established in 1974 by Tyne and Wear County Council, drawing in the collections of the former Newcastle Archives Office, which closed. On the abolition of the county council in the local government reorganisation of 1986 Tyne and Wear Archives Service became a joint service of the five metropolitan districts, managed by Gateshead Council.
Since 1976 Tyne and Wear Archives Service has been located at Blandford House, Newcastle upon Tyne, the former headquarters of the North East Co-op, which it shares with Tyne and Wear Museums and the Discovery Museum.
In April 2009 Tyne and Wear Archives Service merged with Tyne and Wear Museums to form Tyne & Wear Archives & Museums.
In December 2013 The National Archives (United Kingdom) announced that Tyne and Wear Archives was amongst the first group of UK record offices to achieve Accredited Archive status.
