Geishöhe, Television and observation tower in Bavaria, Germany.

Geishöhe is a 521 m hill in the Spessart in Bavaria's Aschaffenburg district, between Wintersbach and Wildensee. The hamlet Oberwintersbach lies on its summit plateau. About 60 m west of the summit stands the 13 m Ludwig-Keller-Turm, a lookout tower with two platforms reached by 47 and then 13 more steps.

A first tower stood here from 1899. The Spessartbund built the present Ludwig-Keller-Turm in 1936/37, inaugurated on 5 September 1937, and named it after its former chairman Ludwig Keller (1873–1932). It was thoroughly renovated in 2003.

The hill's name means "goat height". The Ludwig-Keller-Turm is named after Ludwig Keller (1873–1932), a Gymnasium professor and former chairman of the Spessartbund, the rambling and naturalist association that built it. Four marked Spessartbund hiking routes meet at the tower.

The Ludwig-Keller-Turm stands about 60 metres west of the summit at roughly 518.5 m; from the lower platform 47 steps lead up, and a further 13 reach the upper platform at 11.9 m. Four marked Spessartbund hiking routes meet at the tower. A 35 m steel lattice mast with the Geishöhe antennas rises 100 m to the east.

The 13-metre Ludwig-Keller-Turm has two platforms: the lower reached by 47 steps, the upper by 13 more. On the upper platform, 11.9 metres up, stands a post of the Bavarian Surveying Administration marking a geodetic reference point at 531.52 metres above sea level.
