Judith of Bavaria (797– 19 April 843) was the Carolingian empress as the second wife of Louis the Pious. Marriage to Louis marked the beginning of her rise as an influential figure in the Carolingian court. She had two children with Louis, Gisela and Charles the Bald. The birth of her son led to a major dispute over the imperial succession, and tensions between her and Charles' half-brothers from Louis' first marriage. She eventually fell from grace when Charles' wife, Ermentrude of Orléans, rose to power. She was buried in 843 in Tours.
