Otto IV, Count of Burgundy (1248, Ornans – 1302) was the son of Hugh de Chalon and Adelaide, Countess Palatine of Burgundy. By his mother, he was a grandson of Countess Beatrice II of Burgundy. By his father, he was descended from another branch of the Counts of Burgundy.
Upon his father's death in 1266/1267, he became Count of Châlons. His mother, Adelaide, died on March 8, 1279, and Otto inherited the County. However, he was unable to secure real power in the County until 1295. His son and elder daughter Blanche were eventually to succeed him in the County.
His wife Mahaut drew up a contract on June 4 1312 with the famous tomb maker Jean Pepin de Huy to make a tomb. The contract specifies a tomb made of stone and alabaster. Otto was to be shown as an armed knight with a sheld, sword and armor. A lion was shown beneath his feet. Two angels would support the pillow under his head. This tomb no longer exists today, but the designs were preserved. [1]
He married Philippa of Bar in 1271. The marriage was childless.
He married his second wife, Mahaut of Artois, in 1285. They had three children:
| Preceded by Adelaide of Burgundy |
Count of Burgundy 1279–1302 |
Succeeded by Robert |
