Ebbo (or Ebo) (c. 775 – 20 March 851 in Hildesheim) is archbishop of Rheims from 816 until 835 and again from 840 to 841.

He was born a German serf on the royal demesne of Charlemagne.

He is educated at his court and becomes the librarian and councilor of Louis the Pious, king of Aquitaine, son of Charlemagne.

When Louis becomes emperor, he appoints Ebbo to the see of Rheims, then vacant after the death of Wulfaire.
