Antoun Saad (1910 - 26 June 1977) was a Lebanese military and intelligence official. His tenure as head of the Second Bureau from 1958 to 1971 coincided with a period of change and unrest in Lebanon. He was influential in shaping the policy direction and operations of the Lebanese intelligence services, following a doctrine of "absolute security".
Saad was active in various military sectors during his service. He joined the Lebanese Army in 1930.
He served as commander of the second Sniper Regiment (successor to the Levantine Regiment) from 1948 to 1950.
He was married to Barsita Mikhael Saad (born 1926). Together they had six children: Bassam, retired Brigadier General; Hanna, a Business Engineer; Samir, who died at a young age due to malpractice; Elias, a Civil Engineer, Noha; an Endocrinologist; Rita, who died in her early twenties after losing a battle with brain cancer; and Fouad, an Industrial Engineer.
Antoun Saad left the Second Bureau when President Chehab's term of office ended and was appointed commander of the Mount Lebanon Military Region on August 27, 1964, retiring July 1, 1971.
He carried many secrets into retirement, and when the Civil War broke out and his asthma worsened, he burned all classified documents.
He died on 26 June 1977 at the age of 67.
