Judith of Thuringia, a member of the Ludovingian dynasty, was Queen consort of Bohemia from 1158 until 1172 as the second wife of King Vladislaus II. She was the second Queen of Bohemia after Świętosława of Poland, wife of King Vratislaus II, had received the title in 1085.

The Duchy of Thuringia was an eastern frontier march of the Merovingian kingdom of Austrasia, established about 631 by King Dagobert I after his troops had been defeated by the forces of the Slavic confederation of Samo at the Battle of Wogastisburg. It was recreated in the Carolingian Empire and its dukes were appointed by the king until it was absorbed by the Saxon dukes in 908. From about 1111/12 the territory was ruled by the Landgraves of Thuringia as Princes of the Holy Roman Empire. When Frederick IV, the last independent ruler of Thuringia died in 1440, the territory passed to his nephew, the Saxon elector Frederick II.
