The Cathedral of St. Lawrence (Croatian: Katedrala Sv. Lovre) is a Roman Catholic triple-naved basilica constructed in Romanesque-Gothic in Trogir, Croatia. Since its construction lasted several centuries, it illustrates all the styles that succeeded one another in Dalmatia. It serves now as the most imposing monument in the city of Trogir.
The cathedral is part of the historic core of Trogir, which is a UNESCO World Heritage Site.
