Ještěd Tower (Czech: Hotel a televizní vysílač na Ještědu) is a television transmitter on the top of Mount Ještěd near Liberec in the Czech Republic. It is 94 m (308 ft) high. It is made of reinforced concrete shaped in a hyperboloid form. The tower's architect is Karel Hubáček who was assisted by Zdeněk Patrman, involved in building statics, and by Otakar Binar, who designed the interior furnishing. It took the team three years to finalize the structure design (1963–1966). The construction itself took seven years to finish (1966–1973).

The hyperboloid shape was chosen since it naturally extends the silhouette of the hill and, moreover, well resists the extreme climate conditions on the summit of Mount Ještěd. The design combines the operation of a mountain-top hotel and a television transmitter. The hotel and the restaurant are located in the lowest sections of the tower. Before the construction of the current hotel, two huts stood near the mountain summit: one was built in the middle of the 19th century and the other was added in the early 20th century. Both buildings had a wooden structure and both burned to the ground in the 1960s.

The tower is one of the dominant features of the North Bohemian landscape. The gallery on the ground floor and the restaurant on the first floor offers views as far as to Poland and Germany. The tower has been on the list of the Czech cultural monuments since 1998, becoming a national cultural monument in 2006. In 2007 it was entered on the Tentative List of UNESCO World Heritage sites. In 1969 Karel Hubáček was awarded the prestigious Perret Prize of the International Union of Architects (UIA).
