The Federation Tower (Russian: Башня «Федерация») is a skyscraper currently under construction as part of the Moscow International Business Center in Moscow, Russia. Construction of the towers began in 2003. In December 2009, the taller East Tower suffered a height reduction from 360.4 m (1,182 ft) to 242.4 m (795 ft), the same height as the West Tower.

The complex, designed by the German firm NPS Tchoban Voss, is being developed by Mirax Construction and is owned by the Mirax Group. The construction company for the East Tower is the China State Construction Engineering Corporation, while the construction company for the West Tower is Turkish Ant Yapi. The Italian Company Busi Impianti SpA is the contractor for the Mechanical, Electrical and Plumbing Systems of the East Tower. The curtain wall for both towers was designed by the New York office of Thornton Tomasetti under the direction of Jean-Pierre Kocher AIA.

The tower was climbed solo by Frenchman Alain Robert in September 2007.

The Federation Tower complex is divided into two towers:

* East Tower (Vostok), originally designed to be over 506 m (1,660 ft) to the tip of the spire, 93 storeys and 360.4 m (1,182 ft) tall by roof. Later reduced to 242.4 m (795 ft)

* West Tower (Zapad), designed to be 62 storeys and 242.4 m (795 ft) tall.

Several floors of both towers will be utilized by the Global Hyatt Corporation. Bank VTB has opened a US$250 million credit line for the construction of the towers and has bought 33 office floors. Total construction cost for the complex is estimated to be over US$530 million.

Skybridges between Eastern and Western towers will contain restaurants and cafés.
