Apostolic Vicariate of El Beni

The Roman Catholic Apostolic Vicariate of El Beni (or Beni for short) () is an apostolic vicariate (missionary pre-dicoesean jurisdiction), hence exempt, i.e. not subject part of any ecclesiastical province. Its cathedral episcopal see 'Catedral de la Santísima Trinidad' (devoted to the Holy Trinity) is in the city of Trinidad in Bolivia's Amazonian interior.
History.
On 1 December 1917 Pope Benedict XV established as Apostolic Vicariate of El Beni on territory split off from the then Roman Catholic Diocese of Santa Cruz de la Sierra (now an archdiocese).
It lost territory twice in 1942, when Pope Pius XII created the Apostolic Vicariate of Pando and Apostolic Vicariate of Reyes.
Exceptionally for a pre-diocesan jurisdiction, it was repeatedly (since 1781) given an auxiliary bishop, so as to be headed by two titular bishops.
