Liutgard of Saxony (c. 845 - 17 November 885) was Queen of East Francia (see list of Frankish queens and also list of German queens) from 876 until 882 by her marriage with King Louis the Younger.
She was born between 840 and 850, the daughter of the Saxon count Liudolf (805/20 - 866), a progenitor of the Ottonian dynasty (Liudolfings), and his wife Oda of Billung (805/06 - 913).
Liutgard was especially noted for her strong will and political ambition, a reliable supporter of her husband. She is seen as a driving force behind King Louis' struggle with the West Frankish king Charles the Bald around the possession of Lotharingia, culminating in the 876 Battle of Andernach and ending in the final acquisition of the Lotharingian realm by the 880 Treaty of Ribemont.
Before 29 November 874, Liutgard married the Carolingian ruler Louis the Younger (830/835 - 882), second son of King Louis the German, at Aschaffenburg, Franconia. They had two children:
