Mark Moyar (born May 12, 1971) is Senior Advisor at the US Agency for International Development. He served previously as the Director of the Project on Military and Diplomatic History at the Center for Strategic and International Studies, and has been a Senior Fellow at the Foreign Policy Research Institute and a member of the Hoover Institution Working Group on the Role of Military History in Contemporary Conflict.
Moyar was born May 12, 1971 in Cleveland, Ohio to Bert and Marjorie Moyar. He graduated from Hawken School in Gates Mills, Ohio in 1989.
Moyar holds a B.A. summa cum laude in history from Harvard University and a Ph.D. in history from Cambridge University. While a student at Harvard, he wrote for the conservative student newspaper The Harvard Salient. He also played saxophone in the Harvard Jazz Band with legendary saxophonist Joshua Redman.
His articles on historical and current events have appeared in the New York Times, the Wall Street Journal, and the Washington Post. During his time as a Senior Fellow at the Joint Special Operations University (2013-2015), he published three lengthy studies on special operations—in Colombia, Afghanistan, and Mali: Village Stability Operations and the Afghan Local Police (2014), Countering Violent Extremism in Mali (2015), and Persistent Engagement in Colombia (2014) 
Moyar is the author of the 2006 book Triumph Forsaken: The Vietnam War, 1954–1965. In it he argues that Ngo Dinh Diem was an effective leader. Moyar states that supporting the November 1963 coup was one of the worst American mistakes of the war. The other biggest mistakes according to Moyar were: the failure to cut the Ho Chi Minh trail, and the United States Congress' refusal to support the South Vietnamese government after the 1973 Paris Peace Accords were violated, and the refusal of emergency aid to South Vietnam near the end of the war.
Triumph Forsaken caused a great stir and many opinionated reviews, some negative, as well as some positive. In response to the reactions engendered by the book, Andrew Wiest and Michael J. Doidge edited Triumph revisited : historians battle for the Vietnam War (2010), a collection of detailed reviews of the book by 15 different academic historians. The reviews are attached to responses by Moyar, who challenges the criticism of his work.
