The Via Latina (Latin: "Latin Road") was a Roman road of Italy, running southeast from Rome for about 200 kilometers.
It led from the Porta Latina in the Aurelian walls of Rome to the pass of Mons Algidus; it was important in the early military history of Rome. It must have preceded the Via Appia as a route to Campania, in as much as the Latin colony at Cales was founded in 334 BC and must have been accessible from Rome by road, whereas the Via Appia was made only twenty-two years later. It follows, too, a far more natural line of communication, without the engineering difficulties that the arrow-straight Via Appia had to overcome. As a through-route, it preceded the Via Labicana, though the latter may have been preferred in later times.
After their junction, the Via Latina continued to follow the valley of the Trerus (Sacco), following a line taken by the modern railway to Naples, and passing below the Hernican hill-towns, Anagni (where it joined with the Via Praenestina), Ferentino, Frosinone, and others. At Fregellae, it crossed the Liri, and then passed through Aquino and Cassino, both comparatively low-lying towns. It then entered the interval between the Apennines and the volcanic group of Rocca Monfina, and the original road and, instead of traversing it, turned abruptly northeast over the mountains to Venafro, thus giving a direct communication with the interior of Samnium by roads to Isernia and Telese.
