Ještěd, Mountain summit in Horní Hanychov, Czech Republic.

Ještěd is a 1,012-metre mountain southwest of Liberec, topped by a 99.86-metre television tower designed by Karel Hubáček and built between 1966 and 1973. The tower's slender spire rises from a wide conical body, with a ring of small windows near its lower edge and larger openings in the cylindrical base below; a long, low rectangular building with a flat roof extends to its right.

A wooden lookout tower 5 metres tall stood on the summit from 1876, replaced in 1889 by an 8-metre tower. The mountain hotel opened on 13 January 1907, burned down on 31 January 1963, and was replaced by Karel Hubáček's television tower, built 1966–1973 and awarded the Auguste-Perret Prize. The tower has been on the Czech UNESCO tentative list since 2007.

The name Ještěd is first recorded in 1545 as "Jesstied"; the German form "Jeschkenberg" appears in 1565. It probably derives from a word for ash trees once common on the slopes. On 7 August 1870 the summit hosted a tábor lidu, a Czech patriotic gathering from which the Czech Social Democratic Party emerged in 1878.

The cable car from Horní Hanychov has been out of service since a gondola crash on 31 October 2021, so hikers start from the tram terminus of line 3 there. Since June 2024 bus 79 runs from that terminus to the Ještědka car park. A narrow asphalt road climbs from the Výpřež pass, with a parking fee.

Architect Karel Hubáček won the Auguste-Perret Prize for the tower, built 1966–1973 as a 99.86-metre rotation hyperboloid. Jaroslav Rudiš set his 2006 novel Grandhotel here, and in February 2026 the Liberecký kraj bought the building for 181 million crowns.
