The Litorale Romano state nature reserve is a protected area in Lazio (Italy), established by the Ministry of the Environment with Ministerial Decree of March 29, 1996,[1] which includes a large territory of historical-naturalistic interest within the municipalities of Rome and Fiumicino at Tiber Valley.

With its over 17,000 hectares, discontinuously distributed along the Lazio coast [it] between Palidoro and Capocotta, it is the largest protected area overlooking the Mediterranean Sea.

The territory of the reserve, which occupies an area of 17,243 hectares, includes large portions of land (mainly on the coast but also in the inland), encompassing zones of both naturalistic interest – such as the dunes of Palidoro and Capocotta, the oases of Macchiagrande and Castel di Guido or the pine forests of Castel Fusano and Coccia di Morto – and of historical and archaeological importance, such as the excavations of Ostia Antica, the remains of Portus and the coastal towers of the two municipalities (Tor San Michele, Tor Boacciana, Torre Primavera and Torre Perla).

From a hydrographic point of view, the reserve overlooks the Tyrrhenian Sea and is crossed by the rivers Tiber, whose valley and mouth are among the protected areas, and Arrone.
