Villanova University is a private Catholic research university in Villanova, Pennsylvania, United States. It was founded by the Order of Saint Augustine in 1842 and named after Saint Thomas of Villanova. The university is the oldest Catholic university in Pennsylvania and one of two Augustinian institutions of higher learning in the United States (the other being Merrimack College).

The university traces its roots to the old Saint Augustine's Church, Philadelphia, which the Augustinian friars of the Province of Saint Thomas of Villanova founded in 1796, and to its parish school, Saint Augustine's Academy, which was established in 1811. It is classified among "R2: Doctoral Universities – High research activity".
