The Trade Unions Building, or Budynok Profspilok (officially in Ukrainian: Будинок спілок Федерації професійних спілок України, Union house of the Federation of Trade Unions of Ukraine), is a large office building in Kyiv, Ukraine. Located on the city's main Khreshchatyk Street, its façade faces the central Maidan Nezalezhnosti square and contains the city's main clock tower.

The building was built in place of the Noble Assembly building that stood in its place during 1851–1976 and even survived World War II.

The restoration of the building was completed on May 30, 2018, The building has been rebuilt in 2021 and is now visitable.

Maidan Nezalezhnosti's northern half is a unique layout that's topped with a semi-circle with six radial roads. After the destruction of several Khrestchatyk buildings (such as Kyiv City Duma building, Ginzburg building and others) by the Soviet diversion groups^[1] during World War II on 24 September 1941, the square was completely rebuilt in the mid 1950s in a project presided over by architect Alexander Dobrovolsky, in a style to resemble the dominant revival architecture trend, known as Stalinist baroque. In 1956 Moscow issued a decree that challenged the use of excessive decorations in architecture, which stopped existing work before the project could be finished leaving the square with obvious asymmetry, with only the western part completed.

After nearly two decades of such visual dissemblance, in 1974 the XXVth Kyiv's city conference gave a go-ahead to re-develop the city centre and finish the ensemble. The Ukrainian Republican Soviet of Trade Unions (predecessor to the current Federation of Trade Unions of Ukraine) was awarded this prize spot in a draw, and was to sponsor the construction that was carried out by the Kyivmiskbud-4 trust. The building's project, work of Kyivan-native architects Oleksandr Malynovsky and Oleksandr Komarovsky, was a very fine crafted design. This was because it had to match the imposing Kyiv Post Office building opposite not only in proportions, but in such a style that would blend in with the milieu, yet be visibly a modern structure. One feature that punctuated the latter, was a 24-metre tower with four 7.2 x 4.3 metre screens displaying the current time, temperature, date and other information. This became the official clock tower of Ukraine, and chimed the famous melody Yak tebe ne lyubyty, Kyyeve miy. In 2011 the tower was renovated and the screens, being a matrix of almost five thousand 127-Volt, 40 W light bulbs were replaced by diode matrices, providing multi-colour digital image with much greater resolution.

Most of the building was used as offices by the Trade Unions federation, however it contains several auditoriums and banquet rooms that allowed it to be used as a permanent multi-purpose venue.
