Article 25 of the Constitution protects the rights of citizens to practice any religion that they choose. The government also did not establish a state religion. Islam is the predominant religion, practised by approximately 90 percent of the country's population. The majority of the Muslims in the Gambia adhere to Sufi laws and traditions. Virtually all commercial life in The Gambia comes to a standstill during major Muslim holidays, including Eid al-Adha and Eid ul-Fitr. Most Muslims in the Gambia follow the Maliki school of jurisprudence. There is also a Shiite Muslim community in the Gambia, mainly from Lebanese and other Arab immigrants to the region. The Christian community represents about 8 percent of the population. Residing in the western and the southern parts of the Gambia, most of the Christian community identify themselves as Roman Catholic. However, there are smaller Christian groups present, such as Anglicans, Methodists, Baptists, Seventh-day Adventists, Jehovah's Witnesses and small evangelical denominations.
The remaining 1.97 percent of the population adheres to indigenous beliefs, such as the Serer religion. Serer religion encompasses cosmology and a belief in a supreme deity called Rog. Some of its religious festivals include the Xoy, Mbosseh and Randou Rande. Each year, adherents to Serer religion make the annual pilgrimage to Sine in Senegal for the Xoy divination ceremony. Serer religion also has a rather significant imprint on Senegambian Muslim society in that, all Senegambian Muslim festivals such as "Tobaski", "Gamo", "Koriteh" and "Weri Kor", etc., are all loanwords from Serer religion. They were ancient Serer festivals.
Like the Serers, the Jola people also have their religious custom. One of the major religious ceremonies of the Jolas is the Boukout.
Due to immigration from South Asia, there is a presence of Buddhists and followers of the Baha'i Faith
