The World's Largest Cruise Ships: The Top 10 Ranking for 2026

In just one decade, the cruise industry has been engaged in an unprecedented race to build new, gigantic cruise ships. This competition to have the world’s largest cruise ship in service is particularly intense among the fleets of family-owned or popular cruise lines.

These are the 10 largest cruise ships in the world in 2026

We can see that 2026 is shaping up to be an impressive year for mega-cruise ships. Last year, two true behemoths were launched: Royal Caribbean’s Star of the Seas (nothing less than the Icon) and MSC World America-the first world-class ship specifically designed to conquer the North American market. Both are already operating at full capacity and have turned the rankings upside down.

But that’s not all in 2026. In July, the Legend of the Seas-the third ship in the Icon class, which made history as the first mega-cruise liner of its class to sail the Mediterranean-will arrive. And at the end of the year, MSC will launch the MSC World Asia, its third world-class ship, also based in the Mediterranean. This is particularly good news for European and Ukrainian cruise passengers who have been seeking out these maritime giants but who, until now, had to cross the Atlantic if they wanted to sail on these behemoths.

The race for ever-larger ships shows no signs of ending. Plans for even larger vessels that push the boundaries of naval engineering have just been announced. For example, MSC is developing a new “Constellation” class that will surpass the Icon class in size.

These ships are no longer merely a means of transportation but floating vacation destinations that can rival the most luxurious resorts on land.

Icon of the Seas, launched in January 2024, remains the largest cruise ship in the world (and in history), now sharing the title with its two sister ships of the Icon class.

This Royal Caribbean giant can accommodate up to 7,600 passengers and 2,350 crew members. Measuring 365 meters long, 66 meters wide, and with a gross tonnage of 250,800 metric tons, Icon of the Seas continues to set industry standards even two years after its debut.

Among its most notable features is the largest water park at sea, a Category 6 attraction with six record-breaking water slides. It also offers eight unique “neighborhoods,” including Trill Island and Chill Island, as well as more than 40 restaurants, bars, and lounges. It sails year-round from Miami on itineraries throughout the Caribbean.

FUN FACT: It was Royal Caribbean’s first ship powered by liquefied natural gas (LNG) and fuel cells, marking a turning point in the sustainable development of mega-cruise ships.

The top news story of 2025. Star of the Seas is the second ship in the Icon class, which entered service on August 16 from Port Canaveral, Florida. It is essentially a twin of Icon of the Seas, but with its own unique character.

What are the differences? There are new restaurants, such as the Lincoln Park Supper Club (with a Chicago theme, whereas Icon has a New York aesthetic), a renovated food hall featuring barbecue, Thai, and South American cuisine, and the main attraction is… none other than the musical “Back to the Future.” Yes, with a flying DeLorean.

With a gross tonnage of 248,663, it is technically slightly lighter than Icon (250,800 gross tons), but a few centimeters longer.

FUN FACT: Originally, Diana Ross was supposed to be its godmother, but due to a last-minute cancellation, Kelly Gerardi, an American influencer, defense expert, and commercial astronaut known for her suborbital spaceflights with Virgin Galactic, took on the role. The astronaut who will become the godmother of Star Of The Seas.

The big premiere of 2026. Legend of the Seas-the third ship in the Icon class-brings a new feature that is of particular interest to European cruise passengers: it will be the first Icon-class ship to sail the Mediterranean.

Its maiden voyage departed from Civitavecchia (Rome) on July 4, 2026. The itineraries cover the Western Mediterranean, with stops in Naples, Barcelona, Palma de Mallorca, and Marseille. It also offers cruises departing from Málaga and Barcelona.

After the summer season in Europe, in October, it will cross the Atlantic to Fort Lauderdale, where it will sail routes through the Western Caribbean and, for the first time, through the Southern Caribbean, visiting Curaçao and Aruba.

Construction at the Finnish shipyard Meyer Turku is progressing so quickly that Royal Caribbean has postponed the launch date several times. Originally scheduled for August, the ship will now set sail a month earlier.

The main attraction will be the musical “Charlie and the Chocolate Factory,” and the dining section will feature the Hollywoodland dinner club, themed around classic Hollywood’s Golden Age.

FUN FACT: This is the second Royal Caribbean ship to bear this name. The first Legend of the Seas was a Vision-class ship launched in 1995 that sailed until 2017, when it was sold to Marella Cruises, where it continues to operate under the name Marella Discovery 2. It’s a nice tribute, but each ship has its own take on what it means to travel on a cruise ship.

Wonder of the Seas has slipped to fourth place following the debut of the Icon-class ships, but it remains a true marvel of maritime engineering. Until 2024, it was the world’s largest cruise ship, a title it held for two years.

This maritime giant, part of Royal Caribbean’s Oasis class, can accommodate up to 6,988 passengers and 2,300 crew members. Measuring 362 meters in length, 64 meters in width, and with a gross tonnage of 236,857 metric tons, it remains one of the most impressive ships on the ocean.

Among its most notable features are Central Park, a true green oasis in the middle of the ocean, and “Absolute Abyss,” which remains the tallest water slide on a cruise ship. It has 18 decks and offers more than 20 restaurants.

FUN FACT: The Wonder of the Seas boasts the largest family suite on a cruise ship, called the Ultimate Family Suite. This impressive two-story suite covers approximately 105 square meters and can accommodate up to 8 people. If you can afford it, of course.

And here’s the “other” major debut of 2024, one that many people overlook. Utopia of the Seas is the sixth and final ship in the Oasis class, and it has a unique feature that sets it apart from the others: it’s specifically designed for short 3- and 4-day cruises from Port Canaveral.

This means it’s designed as a “floating weekend resort.” All the entertainment is focused so that you can enjoy it to the fullest in just a few days: the Aquatheater with water acrobatics, Broadway shows, the Ultimate Abyss, surf simulators… the list goes on.

With a gross tonnage of 236,860 metric tons, it technically weighs slightly more than the Wonder of the Seas. It is also the first Oasis-class ship to run on liquefied natural gas (LNG), continuing the sustainability trend pioneered by the Icon.

FUN FACT: The Utopia of the Seas has 50 fewer staterooms than the Wonder of the Seas (2,834 vs. 2,867), precisely because all that space is taken up by liquefied natural gas tanks. The price of sustainability.

Oasis of the Seas, the first giant in the revolutionary Oasis class, continues to hold its place in the top 10 with a maximum passenger capacity of 6,780. And this after 17 years at sea-a true feat.

This ship changed everything. When it was launched in 2009, no one could believe that a cruise ship could feature Central Park with real trees or the Aquatheater with open-air water shows. These are concepts we take for granted today, but which were absolutely revolutionary at the time.

Its length of 361 meters, width of 66 meters, and gross tonnage of 226,838 metric tons keep it among the largest ships in the world. It has undergone several renovations, allowing it to remain competitive with much newer ships.

FUN FACT: The Oasis of the Seas has an air-conditioning system so powerful that it could cool 2,000 homes. A fun fact worth sharing at the dinner table during your next cruise.

Allure of the Seas, the sister ship to Oasis, can comfortably accommodate up to 6,780 passengers in its 2,742 staterooms. With the same dimensions as its “sister” ships (361 meters long, 66 meters wide, and a displacement of 225,282 metric tons), this ship offers a similar experience but with its own unique flair.

It’s one of those ships that divides opinion in the cruise community. Some adore the Oasis-class ships for their incredible variety, while others prefer something more intimate and less crowded. It’s a matter of taste.

FUN FACT: The Allure of the Seas consumes 110,000 kilograms of ice and 20,000 bottles of beer every day. These figures alone give you an idea of the logistics involved in operating these massive ships.

The first MSC Cruises ship to make the list, the MSC World America, debuted in April 2025 from Miami and was named the best new ship of the year by several industry publications. Not bad at all for a cruise line that has historically been stronger in the European market.

The difference from its older sibling, the MSC World Europa, is obvious: this ship was designed from start to finish with North American cruisers in mind. More fast food and takeout options, a bourbon bar, a comedy club, a 1920s-style speakeasy… there’s even the first Eataly at sea. But it retains that European and Italian flair that characterizes MSC.

Year-round, set sail on 7-day cruises from Port Miami through the eastern and western Caribbean, each of which includes a stop at Ocean Cay, MSC’s private island in the Bahamas.

FUN FACT: MSC World America features a “G”-shaped bow (Plumb Bow) and a “Y”-shaped stern, which are not only aesthetically striking but also improve fuel efficiency and stability. Engineering with style.

The MSC World Europa, the ship that launched MSC’s World Class, has dropped to ninth place but remains an impressive vessel that paved the way for the entire series.

At 333 meters long, 47 meters wide, and with a gross tonnage of 205,700 metric tons, making it the largest ship in the MSC Cruises fleet at the time and the company’s first to run on liquefied natural gas (LNG).

It regularly sails the Mediterranean, making it particularly accessible to European and Ukrainian cruise passengers, calling at ports that accommodate deep-draft vessels, such as Barcelona, Genoa, and Marseille.

This cruise ship is notable for its impressive “World Promenade”-a 104-meter-long open-air walkway overlooking the ocean and featuring a dry slide that descends across 11 decks (doesn’t that remind you of the one Royal Caribbean added to its ships a few years ago?), the longest at sea. It also boasts seven pools and 13 hot tubs.

FUN FACT: The MSC World Europa was the first cruise ship in history to generate part of its energy using hydrogen fuel cells-a groundbreaking technology in the industry. It was unveiled during the 2022 FIFA World Cup in Qatar, where it served as a floating hotel.

Rounding out the top ten is a ship that hasn’t made its debut yet but will enter service this December. The MSC World Asia is the third ship in the World Class series, and despite its name, it won’t be sailing in Asia. At least not yet.

So why is it called that? MSC has incorporated design elements inspired by Asian art and landscapes throughout the ship. An aesthetic choice, so to speak.

Its technical specifications are virtually identical to those of its sister ships, the World Europa and World America: 215,863 metric tons, 333 meters in length, and a capacity of 6,762 passengers.

FUN FACT: The MSC World Asia will feature the largest MSC Yacht Club built to date (it will be surpassed only by the future MSC World Atlantic in 2027) and a roller skating rink. Yes, roller skates. On a ship (we’ll see what happens if there’s even the slightest wave). Times are changing.
