Clermont-Ferrand Cathedral (Cathédrale Notre-Dame-de-l'Assomption de Clermont-Ferrand) is a Gothic cathedral, and French national monument, located in the town of Clermont-Ferrand in the Auvergne. It is the seat of the Archbishops of Clermont (bishops until 2002).

It is built entirely in black lava stone, which makes it highly distinctive, and visible from a great distance. Its twin spires are 96.2 metres tall, and tower above the town's rooftops.
