Liberec is a city in the Czech Republic. It is on the Lusatian Neisse and surrounded by the Jizera Mountains and Ješted-Kozákov Ridge. It is the fifth-largest city in the Czech Republic.

Liberec was once home to a thriving textile industry and hence nicknamed the "Manchester of Bohemia". For many Czechs, Liberec is mostly associated with the city's dominant Ješted Tower. Since the end of the 19th century, the city has been a conurbation with the suburb of Vratislavice and the neighboring town of Jablonec nad Nisou. Therefore, the total area with suburbs encompasses 150,000 inhabitants. Liberec itself has about 105,000 inhabitants. That makes Liberec the third-largest city in Bohemia after Prague and Plzen.

Liberec's prominent buildings are the Town Hall (1893), the Liberec Castle, built in the 16th century, and the Ješted Tower (1968) upon the Ješted Mountain, build by architect Karel Hubacek, which became a symbol of the city. Vaclav Havel held a broadcast from the site of the tower in 1968; a plaque beside the tower marks this event. Contemporary buildings of note are also to be found, primarily the work of the firm SIAL, and include the new Regional Research Library (2000) and the Ceska Pojištovna office building (1997). Neo-Renaissance F. X. Šalda theatre was built in 1871–-1872. Centrum Babylon Liberec include a large water park, an amusement park, a casino, shopping court and hotel.
