Queen Judith (795/797 or 805 – 19 April 843), also known as Judith of Bavaria, is the daughter of Count Welf and Saxon noblewoman, Hedwig, Duchess of Bavaria (780–826).

She is the second wife of King Louis the Pious, which garners her the title of Empress of the Franks.

Indeed, this marriage to Louis marks the beginning of her rise as an influential figure in the Carolingian court.

She has two children with Louis, a daughter named Gisela and a son named Charles, more famously known as Charles the Bald.

The birth of her son leads to a major dispute in imperial succession, which leads to tensions between her and Charles' half-brothers from Louis' first marriage.

She eventually falls from grace when Charles' wife, the new empress Ermentrude of Orléans, rises to power.

She is laid to rest in 843 in Tours.
