Ermentrude de Roucy (c. 951 – 5 May 1005) (Irmtrude) was a Countess and Duchess of Burgundy.

Ermentrude was a daughter of Renaud of Roucy and his wife, Alberade of Lorraine, daughter of Gilbert, Duke of Lorraine.

By 971, Ermentrude married Aubry II of Mâcon and thus became a countess of Mâcon. They had:

• Létaud, archbishop of Besançon;
• Aubry, abbot of Saint-Paul de Besançon;
• Béatrice de Mâcon (d.1030), who was married in 975 to Count Geoffrey I of Gâtinais, and afterwards to the Count Hugues du Perche;
• Perhaps a daughter, N de Mâcon, the putative spouse of Eble de Poitiers, son of William IV of Aquitaine and Emma of Blois; they were possibly the parents of Ebles I of Roucy and all of his siblings, including Yvette de Roucy, the wife of either Manasses II or Manasses III of Rethel.

Ermentrude also married Otto-William, Count of Burgundy. They had:

• Guy I of Mâcon
• Matilda, married Landri of Nevers
• Gerberga, married William II of Provence
• Reginald I, Count of Burgundy
• Agnes of Burgundy, Duchess of Aquitaine, married William V of Aquitaine

Adelaide-Blanche of Anjou (c. 940 –1026) was, by her successive marriages, countess of Gévaudan and Forez, of Toulouse, of Provence, and of Burgundy, and queen of Aquitaine. She was the regent of Gevaudan during the minority of her sons in the 960s, and the regent of Provence during the minority of her son from 994 until 999.
