The Warship Support Agency (WSA) was a non-executive agency within the Defence Logistics Organisation (DLO) of the UK Ministry of Defence. It was created on 1 April 2001 from the amalgamation of the "Naval Bases and Supply Agency" and the "Ship Support Agency" and had its headquarters initially in Bath, England, but later moved to the MoD Abbey Wood site in Bristol. As well as project teams the WSA operated the three naval bases in Portsmouth, Plymouth and on the Clyde. The WSA was disbanded in 2005 as part of a major restructuring exercise and became part of the Defence Logistics Organisation.
