Žacléř (Czech pronunciation: [ˈʒatslɛːr̝̊]) (German: Schatzlar) is a town in Trutnov District in the Hradec Králové Region of the Czech Republic. It has about 3,100 inhabitants. The historic town centre is well preserved and is protected by law as an urban monument zone.

The villages of Bobr and Prkenný Důl are administrative parts of Žacléř.

Initially, the settlement was called Bornflos (meaning "mountain creek" in Middle High German) and Bernstadt ("Bern's town"), and Schatzlar was only the name of the local castle, but the name of the castle was eventually transferred to the whole town. The origin of the name Schatzlar is unclear. It could be derived from the German word Schatzsammler ('treasure collector') or from the Middle High German words Schatz ('tax', 'fee') and lar ('settlement'). The Czech name Žacléř is a transcription of the German name.

Žacléř is located about 10 kilometres (6 mi) north of Trutnov and 50 km (31 mi) north of Hradec Králové. It borders Poland to the north. The eastern part of the municipal territory with the built-up area lies in the Broumov Highlands. The western part lies in the Giant Mountains and most of this territory is protected as the Krkonoše National Park. The highest point is the mountain Dvorský les at 1,036 m (3,399 ft) above sea level.

Žacléř was founded on the Silesian trail, which was a trade route from Trutnov to Wrocław. A guarding castle for the protection of the trail was built here probably during the reign of King Ottokar II, around 1260. The first written mention of the castle is from 1334.

From 1570, hard coal was mined here and from 1670, beer was brewed here. In the 19th century, the industrialization occurred. Paper mill, glassworks, and factories for textile, ceramics and soda were founded, but almost all operation ended during the 20th century. In 1992, the coal mining ended.

During World War II, the German occupiers operated a women's subcamp of the Gross-Rosen concentration camp in the town. The prisoners were mostly of Jewish women deported from German-occupied Poland and Hungary. The camp was liberated on 8 May 1945, coincidentally the day of the end of World War II in Europe.
