The diocese was erected in 1967, through
Pope Paul VI, separating from the
Diocese of Surigao. The territory of the Diocese of Butuan contained the Province of Agusan del Sur (now the Diocese of Prosperidad) and Agusan del Norte, and
Carmelo Dominador Morelos was its first bishop. The diocese is a suffragan of the
Archdiocese of Cagayan de Oro. On October 15, 2024, the new
Diocese of Prosperidad was carved out of the Diocese of Butuan. The new diocese comprises the province of
Agusan del Sur.
Pope Francis appointed
Ruben C. Labajo, Auxiliary Bishop of
Cebu, as the first ordinary of the new diocese. ==Coat of arms==
