El Masnou is a town in Catalonia, Spain. It is situated on the coast between Montgat and Premià de Mar, to the north-east of the city of Barcelona, in the comarca (county) of el Maresme. The town is both a tourist centre and a (somewhat exclusive) dormitory town for Barcelona.
The main N-II road and a RENFE railway line run through the town, while a local road links it with the A-19 autopista at Alella.
The town center has buildings in a wide range of styles: neoclassical, modernista, noucentista and simply eclectic. The municipal museum has collections of archeology and of Catalan ceramics, and there is also a private museum of pharmacy and medicine. A Roman village called Cal Ros de les Cabres was one of the first settlements located on the site of the current town.
Famous Spanish Cellist Pablo Casals lived in El Masnou.
