Stephen of Liège (also Étienne de Liège; was a Frankish churchman who was the bishop of Liège from 901 until his death in 920. He was a hagiographer and composer of church music. His surviving compositions include three Proper Offices for the Office of the Trinity, the Office of the Invention of St Stephen and the Office of St Lambert. Like the Offices of his contemporary Hucbald, Stephen's compositions follow the eight modes, though the musicologist Yves Chartier does not consider this innovation, asserting that both composers "did no more than to apply openly a manner of composition that was prevalent in their milieu."
