The Freedom class is a group of three cruise ships for Royal Caribbean International. The first ship of the class, Freedom of the Seas, was the largest passenger ship in the world, and the largest ever built in terms of passenger capacity and gross tonnage, when it was built in 2006. These two records were then shared by all three ships until the construction of Oasis of the Seas was completed in November 2009.

The Radiance class is a class of four cruise ships operated by Royal Caribbean built between 2001 and 2004 at Meyer Werft shipyard in Papenburg, Germany. The class was preceded by the Voyager class and succeeded by the Freedom class.
