Teplice (Czech pronunciation: [ˈtɛplɪtsɛ] , until 1948 Teplice-Šanov; German: Teplitz, Teplitz-Schönau) is a city in the Ústí nad Labem Region of the Czech Republic. It has about 51,000 inhabitants. It is the most populous Czech spa town, followed by Karlovy Vary. The historic city centre is well preserved and is protected by law as an urban monument zone.

Teplice comprises the administrative parts of Teplice, Hudcov, Nová Ves, Prosetice, Řetenice, Sobědruhy and Trnovany.

The Old Czech word teplice is an Old Czech word meaning 'warm (hot) water'.

Teplice is located about 14 kilometres (9 mi) west of Ústí nad Labem and 72 km (45 mi) northwest of Prague. The northern part of the municipal territory lies in the Most Basin, the southern part lies in the Central Bohemian Uplands. The highest point is the hill Doubravská hora at 393 m (1,289 ft) above sea level. There are several small fish ponds in the territory.

According to the 1541 Annales Bohemorum by chronicler Wenceslaus Hajek, the thermal springs are fabled to have been discovered as early as 762; however, the first authentic mention of the baths occurred in the 16th century. The settlement of Trnovany was first documented in a 1057 deed, while Teplice proper was first mentioned in 1154, when Judith of Thuringia, queen consort of King Vladislaus II of Bohemia, founded a Benedictine convent near the hot springs, the second in Bohemia. A fortified town arose around the monastery, which was destroyed in the course of the Hussite Wars after the 1426 Battle of Aussig. In the late 15th century, queen consort Joanna of Rožmitál, wife of King George of Poděbrady, had a castle erected on the ruins.

Teplice figures in the history of the Thirty Years' War, when it was a possession of the Protestant Bohemian noble Vilém Kinský, who was assassinated together with Generalissimo Albrecht von Wallenstein in Cheb in 1634. The Habsburg emperor Ferdinand II thereafter enfeoffed castle and town to his general Johann von Aldringen, who nevertheless was killed in battle in the same year, and Teplice fell to his sister Anna Maria von Clary-Aldringen. Consequently, and until 1945, Teplice Castle was the primarily seat of the princely House of Clary-Aldringen. After the Thirty Years' War, the devastated town was the destination of many German settlers.

After a blaze in 1793, large parts of the town were rebuilt in a Neoclassical style. The health resort was a popular venue for wealthy bourgeois like the poet Johann Gottfried Seume, who died on his stay in 1810, or Ludwig van Beethoven, who met here with Johann Wolfgang von Goethe in 1812; as well as for European monarchs. During the Napoleonic War of the Sixth Coalition, Teplice in August 1813 was the site where Emperor Francis I of Austria, Emperor Alexander I of Russia and King Frederick William III of Prussia first signed the triple alliance against Napoleon I of France that led to the coalition victory at the nearby Battle of Kulm.

In 1895, Teplice merged with neighbouring Lázně Šanov (Schönau). Upon the dissolution of Austria-Hungary after World War I and the 1919 Treaty of Saint-Germain-en-Laye, the predominantly German-speaking population found itself in newly established Czechoslovakia. According to the 1930 census there were 30 799 people living in the city (5,232 persons of Czechoslovak ethnicity, 12 persons of Hungarian ethnicity, 23,127 persons of German ethnicity and 667 of Jewish ethnicity). Right-wing political groups like the German National Socialist Worker's Party referred to themselves as Volksdeutsche and began to urge for a unification with Germany, their efforts laid the foundation for the rise of the Sudeten German Party under Konrad Henlein after 1933. With the Sudetenland, Teplice was annexed by Nazi Germany according to the 1938 Munich Agreement and incorporated into Reichsgau Sudetenland. In 1930, 3,213 Jews lived in Teplice, 10% of the population. Under the Nazi regime they faced the Holocaust in the Sudetenland. Many fled and the Teplice Synagogue was burnt during Kristallnacht.

After World War II the Czechoslovak government enacted the Beneš decrees, whereafter the German-speaking majority of the population was expelled from Teplice. In 1945, the Princes of Clary-Aldringen, lords of Teplice since 1634, were expropriated.

In 1994, Jaroslav Kubera of the ODS became mayor of Teplice and he held the position until 2018.

The largest employers based in the city are AGC Flat Glass Czech (manufacturer of flat glass for the construction and automotive industries) and Severočeská servisní (a company that deals with construction and maintenance of pipelines), both with more than 1,000 employees.

One of the most important employers is the spa. The thermal mineral springs were mentioned already in 1154, which makes the spa the oldest in the country and Central Europe. The Pravřídlo spring reaches a temperature of 41 °C. The spa focuses on treatment of musculoskeletal disorders, nervous system diseases, and vascular diseases.

The city used to be nicknamed "Little Paris" and "Salon of Europe" for its spa architecture and cultural level until World War II. The opening of the spa season is an annual three-day celebration with a rich cultural program. The Krušnohorské Theatre is the city's main venue for operas and plays.

Teplice is home to the professional football club FK Teplice playing in the Czech First League. The stadium Na Stínadlech is one of the largest in the country and has hosted international matches.

The main landmark is Teplice Castle. It houses a regional museum with historic castle interiors and a library. In the inner courtyard of the castle, there is a unique Romanesque exposition with the remains of Queen Judith and the remains of a Romanesque basilica with a rarely preserved Romanesque crypt. Adjoining the castle is a large castle garden.

The Church of Saint John the Baptist is a baroque building from 1594, rebuilt in 1703 to its current form. Its tower is open to the public and serves as a lookout tower.

The neo-Gothic Church of Saint Bartholomew was built in 1884 for German population of Lutheran faith. After their expulsion, the church changed owners several times and ceased to serve its purpose. Today it is conserved as a cultural monument and there are expositions concerning the history of the Jewish community in Teplice, and other.

Doubravka Castle is a castle ruin located in Trnovany part of Teplice. It was built in 1483 and conquered in 1639 during the Thirty Years' War. The castle began to serve as a destination for walks and in the 19th century, a restaurant and the neo-Gothic extension were built. Today there is a restaurant and a private lookout tower.

Fossils of an elasmosaurid plesiosaur (large carnivorous marine reptile from the Cretaceous period) were found near Teplice at the end of the 19th century. In the village of Hudcov (a part of Teplice), plesiosaur Cimoliasaurus teplicensis was described in 1906 by Czech paleontologist Antonín Frič.
