The Radisson Blu Royal Hotel is a historic hotel in Copenhagen, Denmark, that was designed by Danish architect and designer Arne Jacobsen for the airline Scandinavian Airlines System (SAS) between 1956 and 1960.

Built as the SAS Royal Hotel, the hotel was renamed the Radisson SAS Royal Hotel in 1994, when SAS bought a share in the foreign division of Radisson hotels. When SAS sold their share in 2009, it was renamed the Radisson Blu Royal Hotel, its current name.

At its completion the hotel was the largest in Denmark. At 69.60 meters in height, it was the first skyscraper in Copenhagen, and until 1969 the tallest high-rise building in Denmark.
