The name Air Wales (Welsh: Awyr Cymru) has been used by two airlines. The first Air Wales was an airline operating flights between Cardiff International Airport and Hawarden Airport in Flintshire commencing in 1977 and ending 18 months later. The second Air Wales was an entirely separate unrelated airline also based at Cardiff International Airport in Rhoose, Vale of Glamorgan. It operated scheduled regional services within Great Britain, as well as to Ireland, Belgium and France. On 23 April 2006, Air Wales ceased all operations, citing "spiralling costs" and "aggressive competition" from larger low-cost airlines.

The first airline to use the name "Air Wales" was founded in August 1977 by aircraft brokers DK Aviation and Orbit Trust. It began operations at Cardiff Airport on 6 December 1977 using a 9-seater Piper PA-31 Navajo Chieftain (G-BWAL) on its twice-daily scheduled route from Cardiff to Hawarden Airport, Flintshire - a destination which was billed as "Chester" (even though Hawarden is in Wales and Chester is the other side of the Welsh/English border). Clwyd County Council provided the company with a start-up grant of £10,000 on the grounds that the service would improve communications between North East Wales and Cardiff. The single fare was £16.50p. Notwithstanding the confined space of the aircraft, complimentary coffee was routinely served in-flight to passengers by the First Officer. The airline added services from Cardiff to Cherbourg and Brest in France. In 1978 an Embraer EMB-110 Bandeirante (G-CELT) was added to the fleet to operate a service from Cardiff to Brussels connecting into Sabena's network. However, with break-even estimated at some 15 months away, Air Wales, unable to raise sufficient working capital, ceased operations on 30 June 1979 and became part of Air Anglia and ultimately part of Air UK.

The second manifestation of "Air Wales" was a much larger operation established in January 1997 with the assistance of property financier Roy Thomas and started operations in January 2000. Initially based at Pembrey Airport in west Wales and operating two Dornier 228 aircraft, Air Wales expanded to employ over 120 personnel, including 45 flight deck staff, 20 engineers and 20 cabin crew.
