Stephen of Penthièvre, Count of Tréguier, 3rd Lord of Richmond (1058/62 – 21 April 1136) was a Breton noble and a younger son of Odo, Count of Penthièvre[1] and Agnes of Cornouaille, sister of Hoël II, Duke of Brittany. In 1093, he succeeded to the title of Count of Tréguier; in 1098, he succeeded his brother Alain as Lord of Richmond in Yorkshire, England.

He died on 21 April 1136 and was buried in the Abbey of St Mary at York.
