The Lebanese Academy of Sciences, known officially by its French name Académie des Sciences du Liban (ASL), is a learned society dedicated to promoting the growth, invigoration, and dissemination of the sciences in Lebanon, and to fostering a world-class scientific culture in the country.

The ASL was recognized by a decree[1] of the Government of the Republic of Lebanon in August 2007.

The first meeting of the ASL's Executive Committee was held in Beirut, Lebanon on October 29–31, 2008.

The ASL is broadly fashioned after the French Academy of Sciences.

The members of the ASL are Lebanese scientists working inside and outside of Lebanon, as well as distinguished foreign scientists, including some who are of Lebanese origin, or who are keen to contribute to the growth of the sciences in Lebanon.
