The Gesta episcoporum Leodiensium is a history of the diocese of Liège written by the monk Gilles of Orval between 1247 and 1251. At about the same time, Gilles also composed an epitome of his history, the Gesta episcoporum Leodensium abbreviata. It was first edited by Johannes Heller for the Monumenta Germaniae Historica in 1880.
