The Archdiocese of Galveston–Houston (Latin: Archidiœcesis Galvestoniensis–Houstoniensis) is a Latin Church ecclesiastical jurisdiction—an archdiocese—of the Catholic Church in the United States. The archdiocese covers a portion of Southeast Texas, and is the metropolitan see of the ecclesiastical province covering east-Texas. The archdiocese was erected in 2004, having been a diocese since 1959 and the "Diocese of Galveston" since 1847. It is the second metropolitan see in Texas after the Archdiocese of San Antonio.

The mother church of the archdiocese is St. Mary Cathedral Basilica in Galveston; the co-cathedral is the Co-Cathedral of the Sacred Heart in Houston. The patron saint is Our Lady of the Immaculate Conception.

Pope Francis named Joe Vásquez as archbishop on January 20, 2025. The archdiocesan chancery is located in Houston.
