Fairuz نهاد حداد‎ (b. 21 November 1935) is a Lebanese singer, and one of the most famous singers of all time in the Arab world. Her stage name (also spelled Fairouz or Fayrouz) literally means "turquoise".

Fairuz was born Nouhad Haddad in Jabal al Arz, Lebanon. She began her musical career as a teenager. From chorus girl at the Lebanese radio station in the late 1940s, to critical and popular acclaim from the 1950s to today, Fairuz is acknowledged not only for her musical talent and contribution, but also as a cultural and political icon. A symbol of a people, a heritage, a quest for peace, and of humanity. During most of her career, Fairuz reflected two other great artists, Assi and Mansour Rahbani. They wrote the lyrics and composed her tunes. Today, many of her songs reflect the composing talent of Ziad Rahbani who is Fairuz's son. Her songs testify to the Rahbani musical genius, as well as to Fairuz's broad musical background. Referred to as "The Soul of Lebanon" in the 1970s, Fairuz became a pre-eminent figure, a superstar of current music in the Arab world. Together, the Rahbani family is both a school of music and a cultural phenomenon.
