The Archdiocese of Seattle (Latin: Archidiœcesis Seattlensis) is a Latin Church ecclesiastical territory, or archdiocese, of the Catholic Church in western Washington State in the United States. The diocese was known as the Diocese of Nesqually from 1850 to 1907. The mother church of the archdiocese is St. James Cathedral in Seattle. The former cathedral is the Proto-Cathedral of St. James the Greater in Vancouver. Its archbishop since 2019 is Paul D. Etienne.

The archdiocese succeeded to the Diocese of Nesqually headquartered in Vancouver, Washington, established in 1850 as a suffragan diocese of the Archdiocese of Oregon City. In 1903, the episcopal see was moved to Seattle, and the diocese's name was changed to Diocese of Seattle in 1907. The diocese was elevated to metropolitan archdiocesan status in 1951.
