Archbishop Hannan High School is a Catholic, co-ed, high school located in St. Tammany Parish, Louisiana, United States. Its mascot is called Harry The Hawk. The school's motto is Caritas Viniculum Perfectionis, which translates to "charity leads to perfection." It is located in the Roman Catholic Archdiocese of New Orleans.
The school is named for the late Philip M. Hannan, Archbishop of New Orleans from 1965 to 1989.
The old Hannan campus, located at 2501 Archbishop Philip M. Hannan Boulevard in Meraux, was destroyed by Hurricane Katrina in 2005. The campus was situated on Archbishop Philip M. Hannan Boulevard, between East Judge Perez Drive and St. Bernard Highway. The school was completely air-conditioned and included Our Lady of Peace Chapel, separate boys' and girls' athletic facilities (including a baseball stadium, softball field, and lighted football stadium), a large library and media center, a science wing, networked computer laboratories, a state-of-the-art foreign language lab, and a Fine Arts Complex that included a 200-seat auditorium, band room, art studio, and journalism lab.
Before its destruction the old campus was in its seventeenth year in operation as the only Catholic high school in St. Bernard Parish.
Archbishop Hannan athletics competes in the LHSAA.
