Slănic (Romanian pronunciation: [sləˈnik]) is one of the 12 towns of Prahova County, Muntenia, Romania, historically and currently known as a salt extraction center, as well as a spa town, with salt lakes.

As its name (salt in Slavonic) suggests, most of Slănic's history and economy are directly related to the presence of relatively large quantities of salt underground, and even in open air.

Although technically incorrect, the compounded name Slănic Prahova is also being used, especially in other parts of Romania.

This alternative name was probably generated to help discern between Slănic and another Romanian town, Slănic-Moldova.

Other worthwhile tourist objectives, all within easy reach for any untrained hiker, are a local water spring named The Cold Fountain (Fântâna Rece), the TV Relay Tower (Releu) beyond The Fir Forest (Pădurea de Brazi), Beacon's Hill (Dealul cu Semn), The Salt Mountain (Muntele de Sare) with the legendary Bride's Cave (Grota Miresei), now partially collapsed due to rain erosion, as well as The Green Rock (Piatra Verde) and The Colt's Small Hill (Delușorul Mânzului).
