Renaud III (c. 1093 – 1148), son of Stephen I (Tête-hardi) and Beatrix of Lorraine, was the count of Burgundy between 1127 and 1148. Previously, he had been the count of Mâcon since his father's death in 1102, with his brother, William of Vienne.
He proclaimed independence from the Holy Roman Emperor Lothair III, but was defeated by King Conrad III of Germany and forced to relinquish all his lands east of the Jura. The name of the region Franche-Comté is derived from his title, franc-compte, meaning "free count".
About 1130, he married Agatha of Lorraine (d. April 1147), daughter of Simon I, Duke of Lorraine.
Beatrice became countess of Burgundy on her father's death.
