Garden Tower is a high-rise building in the Innenstadt district of Frankfurt, Germany.

It was built between 1973 and 1976 as the headquarters of Landesbank Hessen-Thüringen (Helaba) and was one of the first high-rise buildings in Frankfurt's financial district, the Bankenviertel.

The building, designed by architecture firm Novotny Mähner Assoziierte, was commonly referred to as Helaba-Hochhaus until Helaba moved to a new location, the 200-metres-high Main Tower, in 1999.

Most of the office floors provide either direct access to their own garden or enjoy views of the two-storey conservatories.

Today several companies (including the Germany subsidiary of Société Générale, Cerberus Capital Management, Huxley Associates, The Bank of New York Mellon and Frankfurter Sparkasse 1822 Private Banking) are represented in the Garden Tower.
