Otto, Duke of Burgundy

Otto of Burgundy (c. 945–965) was Duke of Burgundy and Count of Auxerre, the second son of Hugh the Great and Hedwig of Saxony, sister of Emperor Otto I. Before Easter 955 his father married him to Liutgarde, heiress of Gilbert of Chalon, and on Gilbert's death in 956 Otto succeeded him.

King Lothair challenged his rule during his minority by occupying Dijon, but recognized him as duke in 960. Otto died in February 965 without children; his brother Henry succeeded him.
