Islam is the largest organized religious community in Guinea-Bissau; there are also Roman Catholic and Protestant churches as well as indigenous religious systems. Estimates vary and do not come from a recent official religious census. A frequently cited estimate for 2020 gives 46 percent Muslims, 31 percent followers of indigenous religious practices, and 19 percent Christians. Religious affiliations may overlap because Islamic or Christian practice is sometimes combined with local beliefs and ancestor rites. Muslim communities are particularly widespread among the Fula (Peuhl) and Mandinka, while Christian communities include Pepel, Manjaco, and Balanta communities, as well as communities in Bissau and along the coast. Depending on the location, access is provided through mosques, churches, Islamic or Quranic schools, denominational schools, and traditional authorities. There is no single public religious authority; in rural areas, distance, local leadership, and institutional availability may affect access. Nationwide-observed celebrations include Eid al-Fitr, Eid al-Adha (Tabaski), Easter, and Christmas. Muslim holidays shift each year according to the Islamic calendar; which days are work-free follows the applicable official state holiday announcement. Public schools are non-denominational, and religious instruction is not provided there. Religious groups may teach within their own communities, and private religious schools are possible. For officially recognized qualifications, however, the government curriculum and validation by the Ministry of Education apply; an exclusively Quranic or Arabic curriculum is not sufficient for this purpose. The Ministry of Justice is responsible for the formal licensing of religious groups and their recognition as associations. In practice, these requirements are not implemented with equal consistency everywhere. The Constitution protects the practice of religion but limits it through constitutional principles; political parties and trade unions may not affiliate with a religious group. The Ministry of Finance is responsible for tax exemptions. Birth and naming rites, initiation, marriage, and burial are organized by local communities; no uniform nationwide religious fee, deadline, or procedure is documented. The legal effect of a marriage or birth, for example, depends on state civil registration and the responsible civil authority, not automatically on the religious rite. Religious leaders often work cooperatively. In 2026, a forum of religious leaders with Muslim, Catholic, Evangelical, and traditional representatives was established, intended particularly to support mediation and peace at the community level. Local conflicts may nevertheless arise: A report for 2023 records 46 cases of violence related to witchcraft accusations and ten deaths. These cases are locally limited and do not constitute a general religious rule of law. In Canchungo, evangelistic activity was suspended after a dispute over ancestor practices; in the east, there are also concerns about religious extremism and foreign funding.
