The Genex Tower (Serbian: Kula Geneks), or Western City Gate is a 35-storey skyscraper in Belgrade, Serbia. It is formed by two towers connected with a two-storey bridge and features a revolving restaurant at the top. With around 140m it is the second-tallest highrise in Belgrade. One of the towers is occupied by the Genex Group. The tower got its popular name "Genex" after this group, while its official title remains Western City Gate. The second, taller tower, is residential.

The left side of the Genex tower is abandoned, but still keeps the Zepter Logo on the top of the commercial side while the right (residential side) is still populated. On the bottom of Genex there have spawn up some shops, like a craft beer shop and shisha bar. The bottom of the building is covered in graffiti but the rest is in a good shape. There is a restaurant on top of the building which while built was intented to spin but sadly it next worked. The restaurant has been closed for quite some time now.
