Protestants in Haiti are a significant minority of the population. The CIA Factbook reports that around 16% of the population is Protestant (Baptist 10%, Pentecostal 4%, Adventist 1%, other 1%). Other sources put the Protestant population higher than this, suggesting that it may form one-third of the population today, as Protestant churches have experienced significant growth in recent decades. 
Protestant churches of significant size include the Assemblées de Dieu , the Convention Baptiste d'Haïti , the Seventh-day Adventists , the Church of God (Cleveland) , the Anglican/Episcopal Church , the Methodist Church in the Caribbean and Americas , the Church of the Nazarene and the Mission Evangelique Baptiste du Sud-Haiti .
Whereas a very small amount of Catholic Haitians combine their faith with aspects of Vodou , this practice is much more rare among Haitian Protestants, whose churches tend to strongly denounce Vodou as diabolical.
