Dominican Republic: Language & Religion

Spanish is the official language of the Dominican Republic, brought to the island of Hispaniola when Spanish colonization began in 1492 and spoken today by the overwhelming majority of the population. Dominican Spanish is rooted in the Andalusian and Canary Islands dialects of southern Spain, but it also preserves words borrowed from the Taíno people who inhabited the island before European contact, including huracán, the source of the English word hurricane. Centuries of contact with enslaved and free Africans further shaped the accent, rhythm, and vocabulary of everyday speech. Haitian Creole is also spoken by a sizable population near the border with Haiti and among Haitian immigrant communities, though it holds no official status.

Roman Catholicism has been the dominant religion since Spanish colonization and remains the largest single denomination, though survey estimates of practicing Catholics vary and have declined in recent decades. Protestant and evangelical churches have grown substantially since the twentieth century and now claim a significant share of the population, particularly Pentecostal congregations. Together, Christian denominations account for the large majority of Dominicans.

Alongside these Christian traditions, an Afro-Caribbean spiritual practice known as Las 21 Divisiones, a Dominican adaptation of Haitian Vodou blended with Catholic and Indigenous elements, is practiced by a smaller and less publicly visible portion of the population. Historically viewed with suspicion by some Dominican Christians because of its associations with Haiti, the practice has nonetheless persisted alongside the country's mainstream religious life, reflecting the same layered mix of Spanish, African, and Indigenous influences found in Dominican language and culture more broadly.
