No. 903 Expeditionary Air Wing Royal Air Force (903 EAW) is an Expeditionary Air Wing (EAW) of the Royal Air Force (RAF). It is currently based at RAF Akrotiri within the Sovereign Base Area on the Mediterranean island of Cyprus, and is tasked with conducting operations against Islamic State of Iraq and the Levant (ISIL) in Iraq and Syria.

Royal Air Force aircraft have been using RAF Akrotiri as their home airbase whilst carrying out these operations. In February 2019, the Tornado GR4 force (previously involving up to ten strike aircraft on rotation) returned to RAF Marham for the type's retirement from service. The Tornado role in theatre is being undertaken by the Typhoon FGR4 detachment. Sentry AEW1 airborne early warning and control (AEW&C) aircraft from No. 8 Squadron were previously employed on operations. However, the aircraft was withdrawn from RAF service in 2021. The previously employed Sentinel R1 ISTAR aircraft from No. V(AC) Squadron was similarly retired in March 2021. In October 2025, two Protector UAVs were reported deployed at RAF Akrotiri. It was the first known international deployment of the type by the RAF.
In early 2024, in response to attacks launched against international maritime shipping by Houthi rebels in Yemen, Royal Air Force Typhoon FGR4 combat aircraft, supported by Voyager KC2/KC3 tanker aircraft, carried out strikes against Houthi forces. Four Cyprus-based Typhoons, carrying Paveway IV laser-guided bombs, and two Voyager aircraft were employed in the strikes.
