The Mid and West Wales Fire and Rescue Service (Welsh: Gwasanaeth Tân ac Achub Canolbarth a Gorllewin Cymru) is the fire and rescue service covering the Welsh principal areas of Carmarthenshire, Ceredigion, Neath Port Talbot, Pembrokeshire, Powys and Swansea.

It was created by a merger of the earlier Dyfed, Powys and West Glamorgan fire brigades.

[1] The service is the largest by area in England and Wales,[2] covering a predominantly rural area of 4,500 square miles (11,700 km2) and the third largest in the United Kingdom behind the Scottish and Northern Ireland fire services.

Since October 2017, the service has shared its control room with South Wales Fire and Rescue Service and South Wales Police at the police headquarters,[3] an arrangement that is expected to save £1 million annually across both fire and rescue services.

[4] The fire authority which administers the service is a joint-board, made up of councillors appointed from Carmarthenshire, Ceredigion, Neath Port Talbot, Pembrokeshire, Powys and Swansea councils.
