The Cathedral of San Juan Bautista is the Roman Catholic cathedral of the Archdiocese of San Juan de Puerto Rico. The cathedral is one of the oldest buildings in San Juan, located in Old San Juan, and is the second oldest cathedral in the Americas.

Even though the Cathedral of Santa María la Menor in Santo Domingo in the Dominican Republic, is an older church building, the Cathedral of San Juan Bautista was the first cathedral church on the Western Hemisphere as San Juan, then known as the city of Puerto Rico, was the first diocese of the New World with bishop Don Alonso Manso in 1511.
