Moisés Carmona y Rivera (October 31, 1912 - November 1, 1991) was a traditionalist Catholic bishop from Acapulco, Mexico who was a proponent of sedevacantism, which holds that the papacy is vacant. Carmona was born in Quechultenango, Guerrero, Mexico, and was ordained a diocesan priest in 1939. Carmona, along with Fathers Joaquin Saenz Arriaga and Adolfo Zamora, formed the Union Catolica Trento. On October 17, 1981, Carmona and Zamora were consecrated bishop by the traditionalist Roman Catholic archbishop Ngô Ðình Thuc, who at the time adhered to sedevacantism.
