Eudes, Count of Penthièvre

Eudes of Rennes (999 – 1079), (Breton: Eozen Penteur) count of Penthievre, was the youngest son of Duke Geoffrey I of Brittany. Following the death of his brother Duke Alan III, Eudes ruled as regent of Brittany in the name of his nephew Conan II, between 1040 and 1062. Eudes married Agnes of Cornwall, sister of Hoel II of Brittany. At least two of Eudes' sons participated in the Norman conquest of England.

• Geoffrey I, count of Penthièvre
• Alain Le Roux
• Stephen, Count of Tréguier married Havise of Guingamp
• Brian, who defeated a second raid in the southwest of England, launched from Ireland by Harold's sons in 1069.

His descendants became the junior branch of the Breton ducal family, which assumed control of the duchy in 1156 under Conan IV of Brittany.
