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.

Historically black colleges and universities (HBCUs) are institutions of higher education in the United States that were established before the Civil Rights Act of 1964 with the intention of primarily serving African Americans. Most of these institutions were founded during the Reconstruction era after the Civil War and are concentrated in the Southern United States. They were primarily founded by Protestant religious groups, until the Second Morill Act of 1890 required educationally segregated states to provide African American, public higher-education schools in order to receive the Act's benefits.
