Transmar was a 10th-century bishop of Tournai and Noyon. Before his appointment to the dual see in 937, he was a monk in the Abbey of Saint-Vaast in Arras and served as provost of his monastery.[1] Both the Abbey of St Peter in Ghent and the chapter of Noyon benefited from his support.[1] He died on 21 March 950 and was buried in the choir of Noyon Cathedral.[1]
