The '''123rd Aviation Regiment''' was an aviation regiment of the United States Army Aviation Branch.

The regiment traced its history to the 123rd Aviation Battalion active during the Vietnam War. Its parent division, the 23rd Infantry Division, became widely known after Company C, 1st Battalion, 20th Infantry (11th Infantry Brigade) led by Lieutenant William Calley slaughtered hundreds of South Vietnamese civilians in the My Lai Massacre in March 1968.<ref>{{cite web|title=My Lai Massacre|url=http://www.history.com/topics/my-lai-massacre|work=History.com|date=9 November 2009 |access-date=20 July 2013}}</ref> A helicopter crew from the 123rd Aviation Battalion, led by Hugh Thompson, Jr., attempted to intervene in the massacre and were later awarded the Soldier's Medal.<ref>{{cite web|last=Goodman|first=Amy|title=Hugh Thompson's Crewmember Remembers Helping to Stop the My Lai Massacre |url=http://www.democracynow.org/2006/1/18/hugh_thompsons_crewmember_remembers_helping_to|work=Democracy Now|access-date=20 July 2013}}</ref> Seymour Hersh broke the story of the massacre in November 1969, and a year later 14 officers – including Samuel W. Koster, the division's commanding officer – were charged with covering the massacre up. Most of the charges were later dropped, but Koster was subsequently demoted and stripped of his Distinguished Service Medal.<ref>{{cite news|last=Stout|first=David|title=Gen. S.W.
