Acerenza Cathedral (Italian: Duomo di Acerenza, Cattedrale di Santa Maria Assunta e San Canio) is a Roman Catholic cathedral dedicated to the Assumption of the Blessed Virgin Mary and to Saint Canius in the town of Acerenza, in the province of Potenza and the region of Basilicata, Italy. It is the seat of the Archbishop of Acerenza.

The cathedral is one of the most notable Romanesque structures in this part of Italy.

The diocese was established by the late 5th century, but the structure of the present Romanesque cathedral building dates from 1080, when construction was begun under archbishop Arnald of Cluny. The site however is far more ancient and traces remain in the present building both of a pagan temple to Hercules Acheruntinus and of the earlier Christian church.

It has a Latin cross ground plan, and three aisles, which terminate in a raised presbytery behind which is an apse with an ambulatory and three radiating chapels, an unusual feature in Italian church design; the transept also terminates at either end in a semi-circular chapel. The ambulatory contains the altar which houses the relics of Saint Canius (or Canus; Italian: San Canio).

The crypt dates from 1524 and contains what is believed to be the sarcophagus of Saint Canius.
