The Archdiocese of Detroit (Latin: Archidiœcesis Detroitensis) is a Latin Church ecclesiastical territory, or archdiocese, of the Catholic Church covering the south-east portion of Michigan in the United States.

The archdiocese consists counties of Lapeer, Macomb, Monroe, Oakland, St. Clair, and Wayne. It is the metropolitan archdiocese of the Ecclesiastical Province of Detroit, which includes all the dioceses in the state of Michigan. In 2000, the archdiocese accepted pastoral responsibility for the Catholic Church in the Cayman Islands.

The Diocese of Detroit was erected on March 8, 1833, and elevated to an archdiocese on May 22, 1937. The Cathedral of the Most Blessed Sacrament has served as the mother church of the archdiocese since 1938. The Basilica of Sainte Anne de Détroit is the second oldest continuously operating Catholic parish in the United States, dating to 1701. In the early 21st century the archdiocese faced a sexual abuse scandal, starting with four priests convicted in 2003 of sexual abuse of minors.
