Odo, second abbot of Cluny (927–942), was noted for his humility and dedication to the Benedictine Rule, which he followed at Cluny and to which he reformed a number of older monasteries which had become lax in observance or even abandoned. He was honoured both by the pope and by his secular neighbours, who made Cluny generous gifts and whom he urged to work for social justice. Much of his life is known from an admiring biography by John of Salerno.
