The Diocese of Saint-Brieuc and Tréguier (Latin: Dioecesis Briocensis et Trecorensis; French: Diocèse de Saint-Brieuc et Tréguier; Breton: Eskopti Sant-Brieg ha Landreger) is a Latin Church diocese of the Catholic Church in France. The diocese comprises the department of Côtes d'Armor in the Region of Brittany. The diocese is currently suffragan to the Archdiocese of Rennes, Dol, and Saint-Malo. The current bishop is Denis Moutel, appointed in 2010.

Originally erected, according to legend, in the 5th century, the diocese was suppressed by the French Revolution. Re-established by the Concordat of 1802, the diocese became a suffragan to the Archdiocese of Tours. Later, in 1850, it became suffragan of the Archdiocese of Rennes. The Diocese of Saint-Brieuc was formed to include: (1) the ancient diocese of the same name; (2) the greater portion of the Diocese of Tréguier; (3) a part of the old Dioceses of St. Malo, Dol, and Quimper and Léon, and (4) the parishes of the Diocese of Vannes. In 1852 the Bishops of Saint-Brieuc were authorized to add to their title that of the ancient See of Tréguier.

In 2022, in the Diocese of Saint-Brieuc and Tréguier there was one priest for every 5,129 Catholics.
