Before the arrival of Spanish missionaries, the people residing in the territory of modern-day Cuba practiced a variety of faiths. Today, Christianity is the most widely professed religion in Cuba, with Catholicism being its largest denomination. A significant share of the Cuban population is either non-religious or practices folk religions.
Cuba's Constitution declares the country a secular state and provides for the separation of religious institutions and the state, but the Cuban Communist Party (CCP), through its Office of Religious Affairs (ORA) and the Ministry of Justice (MOJ), regulates religious practice.
