Vilassar de Dalt (Catalan pronunciation: [biləˈsa ðə ˈðal]) is a village in Catalonia, Spain, in the province of Barcelona and the comarca of Maresme. The name comes from the Roman name Villa Azari, later changed to Vilassar. In the 20th century, it split into two villages: Vilassar in the hills (de Dalt), and Vilassar by the Sea (de Mar).
