The Apostolic Vicariate (or Vicariate Apostolic) of San Miguel de Sucumbíos (Latin: Apostolicus Vicariatus Sancti Michaëlis de Sucumbios) is a missionary entity of the Roman Catholic Church.

Its cathedral see, the Catedral Nuestra Señora del Cisne, is located in the city of Nueva Loja, Sucumbíos Province in Ecuador.

Relations between the two entities were strained and believers within Sucumbíos were divided in those supporting the Heralds of the Gospel and those who did not.

[3] On 5 December 2011, Pope Benedict XVI named Paolo Mietto Apolostic Administrator.
