The Jeonju diocesan territory covers 8,053 square kilometers and includes Jeollabuk-do province.
Jeonju diocese was erected as apostolic prefecture and carved out of Daegu archdiocese on April 13, 1937. It was elevated as apostolic vicariate on Jan. 21, 1957, and then became a diocese on March 10, 1962. Jeonju diocese belongs to the ecclesiastical province of Kwangju which comprises Kwangju archdiocese and Cheju diocese.
It is the first diocese in the Korean Church to be managed by native clergy since its inception.
Jeonju Catholics take great pride in the fact that in 1931, before being established as a prefecture, it was made an episcopal vicariate by the bishop of what would become Daegu archdiocese, then under the pastoral care of the Paris Foreign Mission Society. Jeonju diocese was totally under the control of Korean priests, who could implement personnel management independently.
Martyrs' Mountain in Jeonju is where Augustine Yu Hang-gom(1756-1801) and six of his family members were martyred and buried together during religious persecution in 1801. Augustine Yu is considered the apostle of Honam, the Korean peninsula's southwestern region.
