The Archdiocese of Portland in Oregon (Archidioecesis Portlandensis in Oregonia) is a Latin Church archdiocese of the Catholic Church in western Oregon in the United States.

Established in 1846, it was the second Catholic archdiocese established in the United States after the Archdiocese of Baltimore. In 2004, during a sexual abuse scandal, it became the first archdiocese to file for Chapter 11 bankruptcy.

The mother church of the archdiocese is St. Mary's cathedral of the Immaculate Conception in Portland. As of 2023, the archbishop of Portland is Alexander Sample.
