Established as Loyola College in Maryland by John Early and eight other members of the Society of Jesus in 1852, it is the ninth-oldest Jesuit college in the United States and the first college in the United States to bear the name of St. Ignatius of Loyola, the founder of the Society of Jesus.

Loyola's main campus is in Baltimore and features Collegiate Gothic architecture and a pedestrian bridge across Charles Street.
