What is the 4th largest cruise ship in the world?

The Allure of the Seas is the fourth largest cruise ship in the world, and right now, you'll have to travel to Florida to get onboard.



As of early 2026, the 4th largest cruise ship in the world is the Utopia of the Seas, operated by Royal Caribbean. It has a gross tonnage of approximately 236,857 GT. It follows the Icon of the Seas (#1), Legend of the Seas (#2), and Star of the Seas (#3), all of which belong to Royal Caribbean's newer "Icon" and "Oasis" classes. The Utopia of the Seas is notable for being the first Oasis-class ship to be powered by Liquefied Natural Gas (LNG), making it significantly more environmentally friendly than its older sister ships like Wonder of the Seas (which it effectively tied in size but surpassed in modern tech). For 2026 travelers, the Utopia is marketed as the "World's Biggest Weekend," primarily running short, high-energy 3 and 4-night cruises to the Bahamas, featuring a record-breaking number of pools and the "Ultimate Abyss" slide, which is the tallest dry slide at sea.

A mega-ship, such as Royal Caribbean's Harmony of the Seas, might just be the best cruise ship to avoid seasickness.
