San Mauro Cilento is a town and comune in the province of Salerno in the Campania region of south-western Italy.

Its secondary toponym, Casalsoprano (or Casal Soprano, i. e. Upper Farmhouse),[4] is closely related to the one of the nearby and lower village of Casalsottano (i.e. Lower Farmhouse).

[5] In 1453, after the fall of Constantinople, the wealthy family of the Mazza fled the city and contributed to the construction and continued development of San Mauro Cilento.

San Mauro is a hillside town located in central Cilento, below the Stella mountain (1,131 amsl).

[5] Its municipal territory, part of the Cilento and Vallo di Diano National Park, spans to the coast and borders with Montecorice, Pollica, Serramezzana and Sessa Cilento.
