William I (1020 – 12 November 1087), called the Great (le Grand or Tête Hardie, "the Stubborn"), was Count of Burgundy from 1057 to 1087 and Mâcon from 1078 to 1087. He was a son of Reginald I, Count of Burgundy and Alice of Normandy, daughter of Richard II, Duke of Normandy.{{sfn|Keats-Rohan|1993|p=43}} William was the father of several notable children, including Pope Callixtus II.

In 1057, William succeeded his father and reigned over a territory larger than that of the Franche-Comté itself. In 1087, he died in Besançon, Prince-Archbishopric of Besançon, Holy Roman Empire—an independent city within the County of Burgundy. He was buried in Besançon's Cathedral of St John.

William married a woman named {{Interlanguage link|Stephanie of Burgundy{{!}}Stephanie|fr|3=Étiennette de Bourgogne}} (a.k.a. Etiennette).She was identified as the daughter of Adalbert, Duke of Lorraine in an article by Szabolcs de Vajay in Annales de Bourgogne, XXXII:247–267 (Oct.–Dec. 1960), but the author subsequently made an unqualified retraction of this claim in "Parlons encore d'Etiennette" in Prosopographica et Genealogica, vol. 3: Onomastique et Parenté dans l'Occident medieval, K. S. B. Keats-Rohan and C. Settipani, eds. (2000), pp. 2–6.
