Tyne & Wear Archives & Museums (TWAM) is a regional group of United Kingdom national museums and the county archives service located across the Tyne and Wear area of north-east England. They have been administered by a joint board of local authorities since the abolition of the Tyne and Wear Metropolitan County Council in 1986. In the past the service received additional financial support from the Department for Culture, Media and Sport. Since 2012, core support is provided via the Arts Council England. The service is one of those specified in the Designation Scheme administered by Arts Council England.
