Jitrovník, Mountain summit in Czech Republic.

Jüttelberg (Czech: Jitrovník) is a 510 m granodiorite hill in the Šluknov region of northern Bohemia, near the German border. Its slopes are mostly covered by coniferous and mixed forest, with fields on the lower slopes toward Království. A 31 m steel-and-larch lookout tower stands on the eastern secondary summit, and the foundations of the former Vogelbaude lie below it.

In 1888 Johann Vogel opened an excursion restaurant, the Vogelbaude, on the eastern slope, and a 24-metre wooden lookout tower was built on the summit by the Gebirgsverein für das nördlichste Böhmen; the tower collapsed in 1903. From 1962 to 1990 the former restaurant served as a pioneer camp for ZPA Praha, burned down in 1998 and vanished. Since 18 May 2002 the Fünfgemeinde cross-border association has held annual Whitsun meetings on the mountain.

Since 18 May 2002, the Jüttelsberg meetings of the Fünfgemeinde have been held here every year at Pentecost. Mayors of the cross-border alliance of Neusalza-Spremberg, Friedersdorf, Oppach, Jiříkov and Šluknov signed their declaration of intent on the hill; Sohland joined in 2008 and Ebersbach-Neugersdorf in 2011.

A paved service road climbs from the south, branching off the Šluknov–Jiříkov road, to the foundations of the former mountain hut. A blue-marked trail crosses west–east and a yellow-marked trail north–south over the summit; Czech cycle route 3043 passes just north of the top.

The summit's rock is granodiorite cut by dolerite veins, not basalt. The 31-metre steel-and-larch lookout opened on 26 September 2026 on the site of the 1888 wooden tower, which collapsed in a storm in 1903; it is the northernmost lookout tower in the Czech Republic.
