Josep Vilaseca i Casanovas (Catalan pronunciation: [ʒuˈzɛb ˌbiləˈsɛkə]) (Barcelona 1848–1910) was a Catalan architect and artist who formed part of the Modernista movement.
He studied architecture in Madrid and qualified in 1873. He travelled with Lluís Domènech i Montaner in Germany. By 1874 he was already teaching at the Escuela de Arquitectura de Barcelona, a post he held for the rest of his life.
Amongst his best-known works is the Arc de Triomf in Barcelona, built for the 1888 Universal Exposition. His work is a textbook case of the evolution of late neo-Classicism into Modernisme which took place in Catalan architecture towards the end of the 19th century.
