Benicàssim (Valencian pronunciation: [beniˈkasim], Spanish: Benicasim, Arabic: بنو قاسم according to Numismatic findings) is a municipality embracing a beach resort located in the province of Castelló, on the Costa del Azahar in Spain. The mountain range known as Desert de les Palmes rises inland protecting the town from the north wind. The name is derived from the Berber Banu Qasim tribe, a segment of the Kutama Berbers that settled the area during the 8th century Moorish conquest of Spain.
Benicasim is located 13 km north of the town of Castelló de la Plana, on the north of the Valencian Community. It has a population of 18,098. Its main economic activity comes from tourism; most notably the town is famous for some of the most important artificial beaches in Europe and because of its famous music festivals like FIB or The Rototom SunSpash.
