Ještěd (Czech pronunciation: [ˈjɛʃcɛt]; German: Jeschken) is the highest mountain of the Ještěd–Kozákov Ridge in the north of the Czech Republic, at 1,012 m (3,320 ft). It is the symbol of the city of Liberec.

On the summit is the Ještěd Tower restaurant, hotel and television tower, designed by Karel Hubáček, accessible by road or cable car (Ještěd cable car). The mountain also has a ski resort. From the summit there are views to Germany and Poland.

The name was probably derived from the connection of the Old German words ask and ket, meaning "ash hill" or "ash forest". The Slavic name was created by gradual distortion. The Czech name for the mountain was first recorded in 1545 as Jesstied. The German form of the name, Jeschken, was first mentioned in 1565.

As far back as 1838 the summit hosted a crude stone that serves as a landmark to this day. The first hut on the summit was erected as early as 1844. In the 1860s, the mountain ridge was Station No. 4 of the first order of the Royal Saxon triangulation. For this reason a measuring station was built on the summit.

In 1906, the Mountain Club, a mountain hotel, was built. The Jeschke Horní Hanychov cable car to the summit was opened in 1933.

On 23 August 1940, at midnight, a Heinkel He 111 from the Second (Lion) Squadron (German: Löwengeschwader) from Lüneburg crashed into the mountain near the summit and tore a long swathe in the woods. This accident killed the four crew.

The old mountain hotel burned down in 1963.
