Premià de Mar (Catalan pronunciation: [pɾəmiˈa ðə ˈmaɾ]) is a municipality in the comarca of the Maresme in Catalonia.

It is situated on the coast between El Masnou and Vilassar de Mar, to the north-east of Barcelona.

Like almost all municipalities of Maresme, Premià de Mar has been historically very well connected with the rest of the comarca and with Barcelona thanks to old Camí Ral (Royal Way) (actual N-II main road) and railroad (Barcelona-Mataró railroad route (1848) was the first to be constructed in all the Iberian Peninsula).

The town centre has buildings in a wide range of styles: neoclassical, modernista, noucentista and simply eclectic.

The church of Sant Cristòfol has a baroque doorway with maritime motifs.
