Saint John Vianney College Seminary is a Catholic institution, founded in 1959 by Archbishop Coleman Carroll, the first bishop of the Archdiocese of Miami. It is located in Westchester, a census-designated place of Miami-Dade County, Florida.

The goal of the institution is to form men for the diocesan priesthood by focusing on the pillars of formation: human, spiritual, pastoral, and academic. When the seminary first opened, the curriculum was for four years of high school and then two years of college. After graduation from St. John Vianney, the men were expected to enter a major seminary to continue their journey. In 1976, however, the school changed its format and it is now a four-year college program focusing on philosophy.
