Poggiomarino is a comune (municipality) in the Metropolitan City of Naples in the Italian region Campania, located about 25 km east of Naples.
Poggiomarino originated from the construction the canal "Conte di Sarno", begun in 1592, which would serve the lands of the Tuttavilla family by drawing waters from the Sarno river's springs. The work was completed in the late 17th century, and in the meantime a town had grown from the houses of the workers employed in the construction. Originally named "Taverna Penta", the borough changed his name to Podio Marino in 1738 when the area was acquired by the Genoese merchant Giacomo de Marinis. The population was also increased after the eruption of Vesuvio in 1631.
