The action of 23 August 1967 was a major air battle which involved elements of the Vietnam People's Air Force (VPAF) and the United States Air Force (USAF). The air battle took place over the skies of North Vietnam as part of Operation Rolling Thunder, during the Vietnam War.

On 2 January 1967, the United States Air Force launched Operation Bolo with the aim of luring North Vietnamese MiG fighters into an air battle, where they could be destroyed in an ambush. The operation, led by Colonel Robin Olds, turned out to be a major success after seven North Vietnamese MiG-21 fighters of the VPAF 921st Fighter Regiment were shot down.

Stung by that devastating defeat, the North Vietnamese Air Force grounded their fighter force several times between June and August 1967, in order to work on their training and tactics. On 23 August 1967, the North Vietnamese Air Force employed their newly devised tactic against a U.S. strike formation, while it was conducting raids against a rail yard. The air battle concluded with the USAF losing three F-4D fighters.
