The Voyager class refers to a design of post-Panamax cruise ships owned and operated by Royal Caribbean International.

The Royal Promenade was inspired by Harri Kulovaara, who was VP of Quality Assurance at RCI in the 1990s, who designed a similar feature on a Silja Lines ferry.

They are powered by six Wärtsilä 46 diesel engines, giving a total output of 75,600 kilowatts (101,400 hp).

The class' architecture was assigned to different architects and firms, some of which had no previous cruise ship experience.
