Different varieties of Protestantism and Pentecostalism have been very successful in Latin America, where Chile, Brazil, and most Central American countries are now 15-30 % Protestant. This article analyzes the growth and development of the ten major non-Catholic churches in Chile, one of the most Pentecostal countries of Latin America. It describes the history and growth of the following churches in the chronological order of their arrival or start: Anglicans, Methodists, Seventh-day Adventists, Baptists, Iglesia Metodista Pentecostal, Jehovah's Witnesses, Iglesia Evangélica Pentecostal, Assemblies of God, Church of God, and Latter-day Saints (Mormons). I end with an analysis of average annual growth rates for each church and for the entire Protestant community. Chile was famous for strong Protestant growth in the past, but there are few recent data on church growth. My main question here is: which non-Catholic churches in Chile have been most successful in terms of membership growth and when did this growth occur? The conclusion analyzes why non-Catholic churches in Chile have been successful in the past and why they currently struggle to grow.
