John of Meda was a 12th-century Italian priest and monk belonging to the Humiliati Order. Born Giovanni Oldrati in Meda, he joined the community at the Abbey of Viboldone in 1134 following a vision of the Virgin Mary. He played a significant role in the development of his order, helping to implement the Benedictine Rule and establishing several monasteries across Milan and Lombardy. He eventually served as an abbot in both Milan and Como.
