Xavier University of Louisiana (XULA) is a private, historically black (HBCU), Catholic university in New Orleans, Louisiana. It is the only Catholic HBCU and, upon the canonization of Katharine Drexel in 2000, became the first Catholic university founded by a saint.

Katharine Drexel, SBS was an American Catholic religious sister, and educator. In 1891, she founded the Sisters of the Blessed Sacrament, a religious congregation serving Black and Indigenous Americans.
