Lady Hutton is a former luxury yacht built in 1924 at Friedrich Krupp Germaniawerft in Kiel, Germany. She has now been converted to a hotel and restaurant ship, riding at anchor at the Riddarholmen in Stockholm since 1982. In addition to its size and proximity to the old city, much of the ship’s fame is tied to Barbara Hutton, for whom the ship is named.

Riddarholmen is a small islet in central Stockholm, Sweden. The island forms part of Gamla Stan, the old town, and houses a number of private palaces dating back to the 17th century. The main landmark is the church Riddarholmskyrkan, used as Sweden's royal burial church from the 17th century to 1950, and where a number of earlier Swedish monarchs also lie buried.
