'BMW four-cylinder'), also known as the BMW Tower (German: BMW-Turm or BMW-Hochhaus), is a high-rise building located in the Am Riesenfeld area of Munich, Germany.

It was declared a protected historic building in 1999, and it is often cited as one of the most notable examples of modern architecture in Munich.

The tower has a diameter of 52.30 metres (171.6 ft) and has 22 occupied floors, two of which are basements and 18 of which serve as office space.

BMW badging was also removed from the 2002 sedans, which accompanied Olympic marathon runners during the competition.

The branding was removed again for the building's cameo appearance in the 1975 film Rollerball, replaced by large orange circles, meant to stand for the fictional ruling Energy Corporation of the future.
