The Heinrich Hertz Tower () is a landmark radio telecommunication tower in the city of Hamburg, Germany.
Designed by architect Fritz Trautwein, in co-operation with civil engineers Jörg Schlaich, Rudolf Bergermann and Fritz Leonhardt, the tower was built between 1965–1968 for the former Deutsche Bundespost (German Federal Post and Telecommunications Agency, now s subsidiary ') near ' park. thumb|Heinrich hertz tower seen from Hamburg cathedral.
With an overall height of 279.2 m (916 ft) it is Hamburg's tallest structure, consisting of a 204 m (670 ft) steel-reinforced concrete lower section topped by a 45 m (148 ft) steel-lattice tower and a three-segmented cylinder of about 30 m (98 ft), which supports various antennas. There are eight concentric platforms stacked one above the other: starting at 128 m (420 ft) with the two-story observation (lower floor) and revolving restaurant (upper floor) platform, served by two high-speed elevators. Above that at 150 m (492 ft) is the operations platform housing the workforce and equipment, and further up six differentially sized, smaller open platforms in same distances, populated with high-gain directional microwave radio relay antennas ("parabolic mirrors"). Number nine was added at 25 m height in July 2005.thumb|left|Memorial plaque|346x346px
After the observation platform and restaurant were closed due to asbestos decontamination, former stuntman Jochen Schweizer had a bungee jumping base installed. The restaurant will not open again due to new fire escape regulations, and the bungee platform was closed at the end of 2001.<!-- "jump into death" in Dortmunder Westfalenpark 1½ years later at 2003-07-21 [hd]-->
