Sant Andreu de Llavaneres (Catalan pronunciation: [ˈsant ənˈdɾew ðə ʎəβəˈneɾəs]) is a municipality located 36 km north of Barcelona (Catalonia) (Spain), along the Mediterranean coast, between Mataró and Sant Vicenç de Montalt.

The village has a mixed agricultural and residential character and has become a popular vacation and summer-residence location for people living in Barcelona over the last forty years.

[citation needed] The oldest archaeological remains are from the Neolithic, especially the rocks of "Sant Magí" in the mountains of Montalt.

Between the rivers Llavaneres and les Bruixes, the village Can Sanç dates from Roman times, where vineyards and olive trees were cultivated.

[4] Later called Sant Andreu de Llavaneres, it was part of Mataro and gained independence in the mid-sixteenth century.
