Fernsehturm Waldenburg, Telecommunications tower in Waldenburg, Germany.

Fernsehturm Waldenburg is a 43-metre concrete water tower holding a 300-cubic-metre tank, built in 1959. Until the Waldenburg-Friedrichsberg transmitter took over, a steel lattice mast guyed to the ground carried its antennas on top, giving it a total height of 145 metres and making it Germany's tallest water tower. The mast was removed in November 2009.

The tower was built during the postwar reconstruction period when Germany modernized and rebuilt its broadcasting and telecommunications networks. It became part of a broader effort to equip Baden-Württemberg with contemporary communication infrastructure.

The tower's name, Fernsehturm Waldenburg, recalls its years as a broadcast site for the SDR and, from 1998, the SWR. Its 300-cubic-metre water tank still supplies the town, so the structure is both a utility building and a local landmark above Waldenburg.

The tower is visible from many points in and around Waldenburg, particularly from the surrounding hills and valleys. Since it operates as a technical facility, the interior is not open to visitors, but the structure can be seen clearly from numerous vantage points throughout the region.

The tower was deliberately placed on one of the highest points of Waldenburg to maximize transmission range across the Hohenlohe valley. This strategic positioning makes it an unexpected landmark visible from many kilometers away, serving practical purposes that visitors might not immediately realize.
