Francesco Bonadeo (1458-1495) was an Italian condottiero. The cousin of the Barone di Bonadeo (a fellow condottiero), Bonadeo attempted to reclaim the city of Casale Monferrato from France in 1495, laying siege to the city with his mercenary army. However, his army was slaughtered by Evrart de Balliol and Francoys Becot's French armies, and Bonadeo was slain; Becot became a general after his victory.
