Hugh of Chalon (c. 975 – 4 November 1039) was a member of the house of Chalon. He was bishop of Auxerre and Count of Chalon.
He was the only son of Lambert of Chalon and was made canon of the Cathedral of Autun. After his father death, he was proclaimed bishop of Auxerre in 999 by request of Henry I, Duke of Burgundy. After the death of the latter, he abandoned Auxerre to defend his family county of Chalon in the war that ensued.
