Hroznětín (Czech pronunciation: [ˈɦrozɲɛciːn]; German: Lichtenstadt) is a town in Karlovy Vary District in the Karlovy Vary Region of the Czech Republic. It has about 2,100 inhabitants.

The villages of Bystřice, Odeř, Ruprechtov and Velký Rybník are administrative parts of Hroznětín.

Hroznětín is located about 8 kilometres (5 mi) north of Karlovy Vary. Most of the municipal territory lies in the Sokolov Basin, but it also extends to the Ore Mountains in the north. The highest point is at 812 m (2,664 ft) above sea level. The Bystřice River flows through the town.

The southern part of the territory is rich in fishponds; the largest of them is Velký with an area of about 50 ha (120 acres). It is used for fishing and recreational purposes. There are also flooded kaolin quarries.

The first written mention of Hroznětín is from 1213, when King Ottokar I donated the settlement to Hroznata of Ovenec, founder of Teplá Abbey. After his death is 1217, Hroznětín became a property of the abbey. Around 1333, the village was promoted to a town by King John of Bohemia. In 1434, Hroznětín was bought by Emperor Sigismund, who pawned it to Kaspar Schlick. In 1499, the Jewish getto was established in the town.

The Schlick family owned Hroznětín until 1585, when they sold it to Ernst von Wirsperk. His descendants then sold it to rich burgers in 1603. After Hroznětín was confiscated as a result of the Bohemian Revolt, Duke Julius Henry of Saxe-Lauenburg bought it in 1623. During the rule of Julius Henry and his son Julius Francis, Hroznětín experienced the greatest development. In 1680, the town was acquired by Louis William, Margrave of Baden-Baden.
