Ocna Sibiului (German: Salzburg; Hungarian: Vízakna) is a town in the centre of Sibiu County, in southern Transylvania, central Romania, 10 km (6.2 mi) to the north-west of the county seat, Sibiu. The town administers a single village, Topârcea (Tschapertsch; Toporcsa).

The first spa resort was established here in 1845, and since then Ocna Sibiului has earned a reputation thanks to its heliothermal lakes formed on the site of old salt mines that had collapsed.

There are several salt lakes (former collapsed salt mines) on the salt massif.

The temperate climate, aerosol-rich air, annual temperatures above the regional average, and recent renovations of the spa infrastructure have helped restore the town’s popularity as a health resort.

Ocna Sibiului is also of archaeological interest: Bronze Age tools (dating from approximately 1900–800 BC) have been discovered in the area and are currently exhibited at the Brukenthal Museum in Sibiu.
