Constance of Burgundy (8 May 1046 – 1093) was the daughter of Duke Robert I of Burgundy and Helie de Semur-en-Brionnais. She was Queen consort of Castile and León by her marriage to Alfonso VI of León and Castile. She was the granddaughter of King Robert II of France, the second monarch of the French Capetian dynasty. She was the mother of Urraca of León, who succeeded her father in both Castile and León.

In 1065, Constance married her first husband, Hugh II, Count of Chalon. They were married for fourteen years until Hughes' death in 1079, they had no children.

In late 1079, Constance remarried to Alfonso VI of León and Castile. The marriage appears to have been orchestrated via the Cluniac connections at Alfonso's court. He had previously been married to Agnes of Aquitaine, whom he had either divorced or had been widowed by. The marriage of Constance and Alfonso initially faced papal opposition, apparently due to a kinship between Constance and Agnes.

Constance was instrumental in having the Roman Rite replace the Visigothic rite in the churches of Castile.

Constance and Alfonso had several children but only one of these lived to adulthood:

Constance died in 1093 leaving her fourteen-year-old daughter and her husband a widower. He went on to marry three further wives after her death, but only had a son by his Muslim mistress, Zaida of Seville.

After her death, the corpse of Constance was taken to the town of Sahagún and was buried in the Monastery of St. Facundo and Primitivo, where her husband, King Alfonso VI would be buried along with all his wives.
