The Cathedral of Our Lady of Amiens (French: Cathédrale Notre-Dame d'Amiens), or simply Amiens Cathedral, is a Roman Catholic cathedral and seat of the Bishop of Amiens (currently Jean-Luc Bouilleret). It is situated on a slight ridge overlooking the River Somme in the administrative capital of the Picardy region of France, some 120 km north of Paris.

The cathedral is the tallest complete cathedral in France, its stone-vaulted nave reaching a height of 42.30 metres (138.8 ft) (surpassed only by the incomplete Beauvais Cathedral). It also has the greatest interior volume of any French cathedral, estimated at 200,000 cubic metres (260,000 cu yd). The cathedral was built between 1220 and c.1270 and has been listed as a UNESCO World Heritage Site since 1981. Although it has lost most of its original stained glass, Amiens Cathedral is renowned for the quality and quantity of early 13th century Gothic sculpture in the main west facade and the south transept portal, and a large quantity of polychrome sculpture from later periods inside the building.
