The Douvenant Viaduct (viaduc de Douvenant) is a railway viaduct built between 1903 and 1905 for the Chemin de Fer des Côtes-du-Nord, between the French communes of Saint-Brieuc and Langueux. It was used by the Saint-Brieuc - Moncontour line and the Saint-Brieuc - Saint-Briac line. It was designed by Louis Auguste Harel de La Noë and is the grandest in a series of thirteen "grognet" type viaducts.
