The Matfriede or Matfriedinger, both of which are German terms, is a Frankish noble family of the 9th-11th centuries, or possibly several families who used similar names, that has been proposed by modern historians.
The name of the family is based on the observation that the name Matfried was used by repeatedly by members of this family. However the exact connections between these possible relatives can't for the most part be confirmed by direct evidence.
The first person proposed in this family is Matfried I, a count of Orleans in the time of Louis the Pious. He appears to have had a son also named Matfried.
Adalhard, the ancestor of the second line of Matfrieds, possibly married a daughter or niece of this second Matfried.
