Jamal Al-Atassi (1922−2000) (Arabic: جمال الأتاسي‎) was a Syrian nationalist, politician and author. He was one of the earliest ideologues of the nascent Syrian Ba'ath Party, which he joined soon after it was founded. He helped to lay out its constitution and was the man who came up with the party's motto, "One united Arab Nation with an eternal Message." He also served as chief editor of the party's daily newspaper, Al Baath.
