John the Good (Latin: Ioannes Bonus, Italian: Giovanni Bono or Buono) was Archbishop of Milan from c. 641 to 669. He is honoured as a Saint in the Catholic Church and his feast day is on January 15. It is not exactly known when he became bishop of Milan, but it is believed that his election was in consequence of the 641 conquest of Genoa by the Lombard's king Rothari. John as bishop returned to reside in Milan. John was distinguished for his generosity and charity, from which he was given the sobriquet the Good.
