Blue Skyscraper) is a building located at Bank Square in Warsaw.

Initial concepts for the construction of the skyscraper had been put forward in the 1950s, and construction began in the 1970s and was suspended shortly after the main structure was built.

The unfinished construction was then often called the "golden tower" because of the colour of the facade.

The project was modified by a Belgrade-based company, replacing the copper-coloured facade with colourless reflective material, which gives a clear reflection of the sky (hence the current name, due to the building being blue during sunny weather).

Both of these companies previously installed large signs on the building, which have since been taken down.
