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.

Radiance-class ships have a gross tonnage of 90,090, being smaller than the preceding Voyager class. Built for cruising in cooler climates, this class differs in design from the Voyager and Freedom classes, and some aspects influenced the Quantum class. The Radiance class is built to Panamax form factor, allowing them to pass through the Panama Canal. The power plant on all ships consists of environmentally friendlier but less fuel efficient gas turbines.

The Radiance-class ships have over 3 acres (12,000 m²) of glass, glass exterior viewing elevators, over 700 balcony staterooms, two-level glass windowed dining rooms, alternative restaurants, a retractable glass roof over a pool, an outdoor pool, as well as the first self-leveling billiard tables at sea. During their refurbishment, the ships of this class have been refitted to incorporate the "Centrum Wow" events, which transformed the multi-level atrium into vertical theater for aerialists (aerial gymnasts).
