The Diocese of Saint-Claude (Latin: Dioecesis Sancti Claudii; French: Diocèse de Saint-Claude) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in France. The diocese corresponds in territory to the department of Jura. It was created in 1742, as a smaller area, mostly consisting of some parishes previously controlled by the Abbey of Saint-Claude. Under the Concordat of 1802 the diocese was suppressed and its territory included in the Archdiocese of Besançon; in 1822 it was again made an independent diocese.

The Diocese of Saint-Claude is a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Besançon, and formerly a suffragan of the Archdiocese of Lyon. Its cathedra is Saint-Claude Cathedral, in the episcopal see of Saint-Claude, Jura.
