Gislebertus of Autun (also Giselbertus or Ghiselbertus; French: Gislebert fl. 1115–1135), is a hypothetical French Romanesque sculptor, whose decoration (about 1120–35) of the Cathedral of Saint Lazare at Autun, France – consisting of numerous doorways, tympanums and capitals – represents some of the most original work of the period.
The name, presumably belonging to this sculptor, is inscribed on the west tympanum at the Autun Cathedral, which has led to extensive theoretical work attributing other French sculptures of the period to him. According to a modern theory, the name can belong to the person who commissioned the cathedral (possibly Gilbert, Duke of Burgundy).
