The Roman Catholic Church in Vietnam comprises solely a Latin rite hierarchy, joint in a national episcopal conference, comprising three metropolitan archdioceses and 24 suffragan dioceses.
There are no Eastern Catholic, (missionary) pre-diocesan or other exempt jurisdictions.
There are no titular sees, all defunct jurisdictions have current Latin successor sees.
There formally is an Apostolic Delegation to Vietnam as papal diplomatic representation (residential, below embassy-level), but it is vested in the Apostolic Nunciature to Singapore.
