Malgrat de Mar (Catalan pronunciation: [məlˈɣɾad də ˈmaɾ]) is a municipality in the comarca of the Maresme, in the province of Barcelona, Catalonia, Spain.

Some speculate that the name originates from French soldiers taken prisoner in Hostalric during the Crusade against the Crown of Aragon, who were taken to work "reluctantly" (mal great, in Catalan) According to Bernat Boades, in the Libre dels Feyts d'armes de Catalunya, "He made them go to work in a big tower near the sea.

As they went there reluctantly, they went from Palafolls to work in that land they called Malgrat (reluctantly)" On May 30, 1937, in the middle of the Spanish Civil War, the transport ship Ciudad de Barcelona, carrying volunteer brigadiers, was torpedoed by Italian-flagged submarines and sank in front of Malgrat de Mar about 2 miles from the beach.

Malgrat has hotels, campsites and shops to meet the demands of visitors, mainly centred around the street Passeig Marítim.

In the 18th century there were about 200 men with naval registration with a total of up to 50 ships of one to four tons doing traffic along the coast to Valencia and France.
