Conrad the Younger (died around 876) was a prominent noble in the Carolingian Empire, and member of the Elder House of Welf. He was Count of Auxerre from 858, and Lord of Transjuran Burgundy from 864.Template:Sfn He was a son of count Conrad the Elder and countess Adelaide of Tours.Template:SfnTemplate:Sfn His brother was Hugh the Abbot.

Conrad's father, count Conrad the Elder initially held several counties in Alamannia, most notably the counties of Argengau and Linzgau, north of the Lake Constance. In 858, Conrad's family abandoned their sovereign, king Louis of East Francia, and went over to king Charles of West Francia, who was nephew of Conrad the Elder. They were rewarded by the West Frankish king, and thus Conrad the Elder became the Count of Paris, while his son Conrad the Younger became Count of Auxerre. In the same time, king Louis of East Francia confiscated their old fiefs and lands in Alamannia and Bavaria.Template:Sfn

Conrad the Jounger later recovered the old Burgundian estates of his grand-uncle Otkarius, defeating powerful lord Hucbert of Transjuran Burgundy (c. 864), and then continued to rule that region under the auspices of emperor Louis II.Template:SfnTemplate:Sfn He married Waldrada, by whom he left a son, Rudolf, who succeeded his father as Lord of Transjuran Burgundy, and later became King of Upper Burgundy (888).Template:Sfn Conrad also had a daughter, Adelaide of Auxerre, who married Richard, Duke of Burgundy, and had issue. Some online genealogical sources may have him also married to Judith of Friuli, but there is no source for this, and she is not known to have married to anyone.
