The Apostolic Vicariate of El Beni (or Beni for short) (Latin: Apostolicus Vicariatus Benensis) is a Latin Church missionary ecclesiastical territory or apostolic vicariate.

Its cathedra is in the Catedral de la Santísima Trinidad (devoted to the Holy Trinity), in the episcopal see of Trinidad in Bolivia's Amazonian interior.

On 1 December 1917 Pope Benedict XV established as Apostolic Vicariate of El Beni on territory split off from the then 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.
