She was eldest daughter of duke Robert II of Burgundy (1248-1306) and Agnes of France (1260-1325), herself the youngest daughter of King Saint Louis of France.
1305 she married her cousin once removed, Louis of France, King of Navarre, who 1314 ascended also the French throne as Louis X of France.
She was allegedly caught in adultery, and factually improsoned for the rest of her life.
1315 she was allegedly strangled, after years of inprisonment, in order to allow her husband remarry.
She gave birth to one daughter, Jeanne, who later became queen Joan II of Navarre (1311-1349). Her paternity was nder doubts of bastardy. However, she of course was scion of Marguerite, and thus a full potential heir to Burgundy, as well as carrier of the blood of St Louis.
Half a century later, her rights of ainesse became 1361 important in the premature death of duke Philip I of Burgundy (her grandnephew), since closest Burgundian heirs were descendants of Marguerite and of her sister Joan. Marguerite's grandson and heir Charles II of Navarre claimed the duchy on basis of primogeniture, but Joan the Lame's son John II of France on basis of proximity, being one generation closer to the Burgundian dukes. Charles lost the bid to Duchy of Burgundy.
