The Free Lebanon State (), also known as the State of Free Lebanon, was a short-lived puppet state of Israel that existed from 1979 to 1984 with no international recognition. It was formally declared on by Saad Haddad, a Lebanese military officer and founding commander of the Maronite Christian-dominated South Lebanon Army during the Lebanese Civil War. The Free Lebanon State exercised administrative authority in parts of Southern Lebanon, which was under an Israeli military occupation from 1985 to 2000 following Israel's invasion of Lebanon in 1982. The South Lebanon Army operated under the effective supervision of the Israel Defense Forces, and the Free Lebanon State's authority quickly deteriorated with the death of Haddad in 1984, retaining only a provisional administration.
