Galgenberg, Mountain summit in Heilbronn, Baden-Württemberg, Germany.

Galgenberg is a hill in the Heilbronner Berge, a northwestern spur of the Löwensteiner Berge, rising to about 312 m at its southern summit, roughly 3.8 km east of Heilbronn's city centre. Its upper slopes are wooded, while vineyards cover parts of its western and eastern flanks. The northern summit reaches about 301.7 m, and the Weinsberg Tunnel runs beneath the saddle between the two.

The northern summit holds two burial mounds probably from the Bronze Age. Until 1811 a three-legged gallows stood on the mountain; its foundation walls are 1.2 metres thick and enclose a triangle with an inner width of 7.5 metres. In 1893 excavations in a vineyard just before the execution site found numerous horse skulls along 30 metres, and in 1901 ten skeletons of hanged people came to light.

The name Galgenberg means "gallows mountain", recalling the town's high court that stood here until 1811. Excavations in a vineyard just in front of the execution site in 1893 uncovered numerous horse skulls along a 30-metre stretch; in 1901 further digs brought out ten skeletons of hanged people.

The southern summit, about 312 m high, lies roughly 3.8 km east of Heilbronn's centre; the wooded plateau is reached on foot, and the slopes below carry vineyards. The Weinsberg Tunnel (891.3 m long, opened 1862) runs beneath the saddle at the Kernerruhe, and the SWR transmitter tower stands about 250 m east of the northern summit.

The south summit reaches about 312 metres; the north summit, near the SWR transmitter tower, about 302 metres. Two probable Bronze Age burial mounds lie in the Bürg area, and the 891-metre Weinsberg railway tunnel of 1862 passes beneath the saddle at the Kernerruhe.
