Assi Rahbani (Arabic: عاصي الرحباني; May 4, 1923 – June 21, 1986) was a Lebanese composer, musician, and producer.

Assi Rahbani's musical career began when he obtained a job at the Near East Radio channel (إذاعة الشرق الأدنى).

In 1951, Nouhad Haddad (later known as Fairuz), one of the singers in the radio station's chorus, came to the attention of Halim El Roumi, the musical director.

Both of the Rahbani Brothers composed and both of them wrote lyrics as they always clarified in interviews and as attested by their family members as well as by artists who collaborated and worked with them.

After the Lebanese Civil War erupted, the Rahbanis continued to use political satire and sharp criticism in their plays.
