Isnardo da Chiampo was a 13th-century Italian Dominican priest known for his preaching and asceticism. Born in Chiampo, he joined the Order of Preachers in Bologna, where he was received by Saint Dominic. After studying in Bologna and Milan, he traveled through northern Italian cities to combat heresy. In 1231, he established a convent in Pavia, serving as its first prior. He remained in Pavia for the rest of his life, where he died in 1244.
