The Metropolitan Archdiocese of Boston (Latin: Archidiœcesis Metropolitae Bostoniensis) is a Latin Church ecclesiastical territory, or archdiocese, of the Catholic Church in eastern Massachusetts in the United States. Its mother church is the Cathedral of the Holy Cross in Boston. The archdiocese is the fourth largest in the United States.^[3]

It was formed in 1808, branching off from the Diocese of Baltimore and growing rapidly during the 19th century. Starting in 2002 the archdiocese faced a sexual abuse scandal which touched off investigations of Catholic Church sexual abuse cases throughout the United States.

Richard G. Henning has served as archbishop since October 31, 2024.
