The Metropolitan Archdiocese of Seoul (Latin: Archidioecesis Metropolitae Seulensis, Korean: 서울대교구) is a Metropolitan archdiocese of the Latin Church of the Catholic Church comprising the metropolitan area of Seoul, South Korea, whose province comprises parts of South Korea (which has two more provinces) and all North Korea, yet depends on the missionary Dicastery for Evangelization.

Its Metropolitan bishop as the Archbishop of Seoul resides at his Myeongdong Cathedral in Jung-gu, Seoul. The Archbishop of Seoul is also the Apostolic Administrator of the Diocese of Pyongyang in North Korea.

There are 57 Catholic secretly active parishes in North Korea, but due to the current regime in place, no Catholic priests are permitted permanent residency at the present time.

Pope Francis announced that the Archdiocese will be the host of the 2027 international celebration of World Youth Day.^[2]
