The Roman Catholic Archdiocese of Kota Kinabalu (Lat: Archdioecesis Kotakinabaluensis) is a metropolitan archdiocese of the Latin Church of the Roman Catholic Church in Sabah, a state of Malaysia on the island of Borneo. The archdiocese is the oldest ecclesiastical territory in Malaysia, with a long history slowly rising along with the Catholic population from a prefecture to an archdiocese. Its cathedral archepiscopal see is Sacred Heart Cathedral, Kota Kinabalu. The patron saint of the archdiocese is St. Joseph, Spouse of the Blessed Virgin Mary.
On 5 February 1927 it was renamed the Apostolic Prefecture of Northern Borneo, and lost territory to form the Apostolic Prefecture of Sarawak.
On 14 February 1952 the prefecture was promoted to Apostolic Vicariate of Jesselton, hence entitled to a titular bishop. On 22 March 1962 its name was changed once more to the Apostolic Vicariate of Kota Kinabalu, after its see.
The diocese lost territories twice, to create its present suffragans :
on 17 December 1992 the diocese the Diocese of Keningau with the appointment of Cornelius Piong.
on 16 July 2007 the Diocese of Sandakan with the appointment of Julius Dusin Gitom.
On 23 May 2008, the diocese was elevated to Metropolitan Archdiocese, whose ecclesiastical province comprises the above suffragan dioceses, both formerly part of the original territory of the diocese of Kota Kinabalu: the Diocese of Keningau and the Diocese of Sandakan.
On 21 June 2010, PopeBenedict XVI appointed John Wong Soo Kau, director of the aspirants' formation house in Kota Kinabalu, as Coadjutor Archbishop of Kota Kinabalu. His ordination took place on 1 October 2010.
