The Diocese of Grenoble–Vienne-les-Allobroges (; ) is a Latin Church diocese of the Catholic Church in south-eastern France. The diocese, erected in the 4th century as the Diocese of Grenoble, comprises the department of Isère and the former canton of Villeurbanne (Rhône), in the Region of Rhône-Alpes. In 2006, the name was changed from the diocese of Grenoble to the diocese of Grenoble–Vienne. The current bishop is Jean-Marc Eychenne, appointed on September 14, 2022. Before the French Revolution it was a suffragan diocese of the Archbishopric of Vienne and included the deanery or see at Savoy, which in 1779, was made a bishopric in its own right, with the episcopal seat at Chambéry. By the Concordat of 1801, the bishop of Grenoble was made a suffragan of the Archdiocese of Lyon. Thirteen archipresbyterates of the former Archdiocese of Vienne were affiliated to the Diocese of Grenoble, and there were annexed to it some parishes from the then Diocese of Belley (now Diocese of Belley-Ars), the Diocese of Gap, the Archdiocese of Lyon, and the Diocese of Valence.
