St. John's University prepares students from across the U.S. and around the world for success as ethical leaders in today's global society. More than 20,000 undergraduate and graduate students are enrolled at our five campuses -- 15,092 undergraduates and 5,254 graduate students. Together they represent 45 states and 122 foreign countries. Students at St. John's represent a vast range of nationalities, ethnicities and faith traditions. This fosters the cosmopolitan atmosphere you expect of a world-class Catholic university -- reflecting the remarkable diversity of New York City itself.
