Islam in Lebanon has a long and continuous history. According to an estimate by the CIA, it is followed by 63% of the country's total population. Sunnis make up 31.9%, Twelver Shia make up 31.2%, next to smaller percentages of other Shia branches, such as Alawites and Ismailis. The Druze community is designated as one of the five Lebanese Muslim communities, even though most Druze do not identify as Muslims, and they do not accept the five pillars of Islam.

The Lebanese Druze are an ethnoreligious group constituting about 5.2 percent of the population of Lebanon. They follow the Druze faith, which is an esoteric Abrahamic religion originating from the Near East, and self identify as unitarians.
