Marganit Tower, Military skyscraper in HaKirya, Tel Aviv, Israel.

Marganit Tower is a military skyscraper located in the HaKirya complex in Tel Aviv, featuring 17 stories and a concrete mast supporting telecommunications equipment. The structure rises approximately 138 meters and forms part of the military district.

Marganit Tower was built in 1987 by Solel Boneh, with the upper tower and its cladding designed by architect Yosef Asa, alongside Adam Mazor and Eli Firsht. At completion it was the tallest building in Israel, surpassing Shalom Tower. Its status was later reduced when the Azrieli Towers were built, the round one standing about 50 metres higher.

The tower stands in Camp Rabin, the Kirya compound that houses Israel's military headquarters; the tower itself is an office and communications structure, not the Defense Ministry building. After Prime Minister Yitzhak Rabin was assassinated in 1995, the tower was lit in red for a week. In 2016 the Zik Group built a 25-metre wooden model, one-fifth of the original, at the Tel Aviv Museum of Art, titling it "Masjid HaBitachon" as a critique of the army's presence in civilian space.

The tower stands inside the Rabin Camp compound of HaKirya, a closed military zone, so it can only be viewed from the surrounding streets of Tel Aviv. Look up from the outside: the shaft carries a faded "M.T" marking, and the antenna galleries sit near the top. The 28-centimetre lean is not noticeable from street level.

The 28-centimetre lean was found on 5 April 1989, while the tower was still rising; engineers approved continued work. A plumb line dropped from the top lands 28 centimetres from where it should. The tower was lit red for a week after the assassination of Yitzhak Rabin in 1995.
