Giovanni Jacono (14 March 1873 - 25 May 1957) was an Italian Roman Catholic prelate who served as the Bishop of Caltanissetta from 1921 until he resigned due to age in 1956.
Jacono also served prior to this as the Bishop of Molfetta after World War I and had worked in a trade before entering the priesthood.
He was noted for his kindness and for his humble disposition; his holiness was evident to his flock during his episcopal tenure.His reputation for holiness endured in the decades after Jacono's death and this led to the introduction of his beatification cause in Caltanissetta on 24 October 2007; he was titled as a Servant of God.
Pope Francis named him as Venerable on 7 November 2018 upon confirming that Jacono lived a life of heroic virtue.
