Vorderer Löwendorfer Berg, Hill summit in Brandenburg, Germany

Vorderer Löwendorfer Berg is a 103-meter elevation in the flat Teltow-Fläming region near Trebbin, Brandenburg. The sandy hill is topped by a wooden observation tower that rises from its peak.

The hill formed around 20,000 years ago at the end of the Weichsel glaciation, when gravel, marl and sand were deposited between the Fläming end moraine and the Baruth and Berlin glacial valleys. In the 1920s gliders were launched from the summit with rubber ropes before Schönhagen airfield was built. After the Second World War a wooden ski jump stood on the eastern slope, hosting local competitions into the late 1960s; no trace of it remains, but that slope is still used for sledging in suitable weather.

The hill is the highest point of Naturpark Nuthe-Nieplitz. In the 1920s gliders were launched from the summit with rubber ropes before Schönhagen airfield was built, and after World War II a wooden ski jump stood on the eastern slope, used for local competitions into the late 1960s. In suitable weather that slope still serves as a sledding hill.

The hill is reached from Löwendorf via a blue-marked trail; it also lies on the European long-distance path E10 and on Tour 16 of the 66-Seen-Regionalparkroute. The tower's upper section is closed since December 2021 because of the yellow pore sponge in the wood, so climbing stops at the fifth intermediate level, where the view over the treetops is limited.

The 21.7-metre tower, built in 2011–2012 with 60 m³ of larch wood and about 17 tonnes of steel for roughly 190,000 euros, has 112 steps over seven levels. Since December 2021 the platform and top level are closed because the wood is infested with the yellow pore sponge; climbing is possible only up to the fifth level, where the view over the treetops is limited.
