The 902d Expeditionary Air Refueling Squadron is an inactive United States Air Force unit. It was last assigned to the 70th Bombardment Wing at Clinton-Sherman Air Force Base, Oklahoma, where it was inactivated on 31 December 1969.

The squadron's first predecessor was the 602d Bombardment Squadron. The unit served for a time as a training unit before deploying to the European Theater of Operations, where it saw combat during World War II as an element of Eighth Air Force. The squadron participated in the strategic bombing campaign against Germany before returning to the United States in 1945, where it was inactivated.

The 902d Air Refueling Squadron served with Strategic Air Command (SAC) at Clinton-Sherman starting in 1958. It maintained an alert status to refuel SAC bombers and deployed aircraft and aircrews to support Operation Chrome Dome and to Southeast Asia to support Operation Arc Light and participated in the Young Tiger Task Force supporting tactical aircraft in Southeast Asia until it was inactivated.

In 1985 the 602d Bombardment Squadron and the 902d Air Refueling Squadron were consolidated into a single unit. The consolidated unit was converted to provisional status in February 2001 as the 902d Expeditionary Air Refueling Squadron.

The 602d Bombardment Squadron was activated at Ephrata Army Air Base, Washington, in early 1943, as one of the four original squadrons of the 398th Bombardment Group. The squadron trained under II Bomber Command with Boeing B-17 Flying Fortresses. The squadron's training was interrupted in July 1943, when it became a replacement training unit. Replacement training units were oversized units which trained aircrews prior to their deployment to combat theaters. In November, replacement training ended and the squadron resumed its preparation for overseas deployment.
