Colle di Val d'Elsa Cathedral (Italian: Duomo di Colle di Val d'Elsa; Concattedrale dei Santi Alberto e Marziale) is a Roman Catholic cathedral in Colle di Val d'Elsa, Tuscany, Italy. Anciently a pieve of the Holy Saviour (San Salvatore), it is now dedicated to Saints Albert and Martial. Formerly the episcopal seat of the Diocese of Colle di Val d'Elsa from its creation in 1592, it is now a co-cathedral of the Archdiocese of Siena-Colle di Val d'Elsa-Montalcino.
Construction started in 1603 on the site of the old parish church of San Salvatore, expanded during the 11th century by Pisan workers.
Usimbardo Usimbardi, the first bishop of the new Diocese of Colle di Val d'Elsa created in 1592, entrusted the design of the new cathedral to the architect Fausto Rughesi.
The building has a Greek cross plan with a nave and two aisles, divided into four bays by rectangular piers. The transept is closed by two large side-chapels.
