Saint Bononio (or Bononius) (died August 30, 1026) was a Benedictine abbot and saint of the Catholic Church. Bononio was born in Bologna sometime in the latter part of the tenth century. He became a monk at an early age, and while on a pilgrimage to the East settled in Egypt to live as a hermit during the reign of Fatamid Caliph Al-Aziz Billah. Noted for both his asceticism and charitable works, Bononio acquired some influence at court, and was permitted to build a few churches. When Peter, bishop of Vercelli, was captured by Arab forces after the Battle of Stilo, Bononio assisted in the bishop's release, and then retired to live as a hermit in the Sinai.
