Biggest Cruise Lines in the World and Who Owns Them

The biggest cruise line in the world by passenger capacity is Royal Caribbean International, with 29 ships and about 111,000 lower berths. Carnival Cruise Line also runs 29 ships, with 94,340 berths. Both belong to larger groups. Carnival Corporation, which owns eight brands including Carnival, Princess, Holland America and Cunard, is the biggest cruise company in the world, with 94 ships and 272,380 berths. Royal Caribbean Group is second. MSC Cruises, the largest privately owned line, and Norwegian Cruise Line Holdings round out the big four. The full ranking with sources is below.

The industry is more consolidated than the number of brands suggests. Knowing who owns what helps you compare products, understand loyalty programs, and see when “switching cruise lines” means more or less than you expect.

What cruise lines does Carnival own?

Carnival Corporation owns eight active core brands: Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, Costa Cruises, AIDA Cruises, P&O Cruises (UK), and Cunard. It is the largest cruise company in the world by passenger count, revenue, and fleet size, and trades on the NYSE and London exchanges. Despite shared infrastructure, each brand keeps its own identity and market.

Carnival Cruise Line is the flagship, the most-sailed line in North America, known for value pricing and a lively “Fun Ship” atmosphere. It targets first-timers and families, with home ports across the U.S. coasts. Budget to mid-range.
Princess Cruises is the mid-to-premium brand, known for globe-spanning itineraries, a strong Alaska program, and the “Love Boat” legacy. Mid-range to premium.
Holland America Line, founded in 1873, is one of the oldest lines, associated with classic elegance, longer voyages, and enrichment programming. Mid-range to premium.
Seabourn is the ultra-luxury brand: small ships, high service ratios, all-inclusive pricing, and expedition vessels for polar regions.
Costa Cruises is the European mass-market brand, sailing mostly from Italian ports. It is far less visible in North America since the 2012 Costa Concordia disaster, but remains one of the largest lines in Europe.
AIDA Cruises targets German-speaking travelers with a casual, club-resort feel and sails mainly in European waters.
P&O Cruises (UK) is among the oldest cruise lines, tracing its origins to 1837, with a product tailored to British passengers sailing from ports like Southampton.
Cunard is the ocean liner brand. Queen Mary 2 is one of the few true ocean liners in service and runs transatlantic crossings between Southampton and New York, with a level of British formality, such as formal nights and ballroom dancing, that no other brand matches.

Royal Caribbean Group

Royal Caribbean Group (NYSE: RCL) is the second-largest cruise corporation and builds some of the largest ships ever, such as Icon of the Seas and Wonder of the Seas. It runs three brands.

Royal Caribbean International is the flagship, with huge ships packed with rock walls, surf simulators, water parks, and more, aimed at families and active travelers. Mid-range to premium.
Celebrity Cruises is the premium brand, with a more refined atmosphere, strong food, and destination-focused itineraries, including the Galapagos.
Silversea Cruises, acquired by Royal Caribbean Group in 2018, is an ultra-luxury line with all-suite ships, butler service, all-inclusive pricing, and expedition vessels.

Norwegian Cruise Line Holdings

Norwegian Cruise Line Holdings (NASDAQ: NCLH) is the third major corporation, with three brands at very different price points.

Norwegian Cruise Line pioneered “Freestyle Cruising,” dropping fixed dining times and dress codes. Its large ships emphasize specialty dining and entertainment, and Great Stirrup Cay is its private island in the Bahamas. Mid-range.
Oceania Cruises is the premium brand, with mid-sized ships, destination-intensive itineraries, and a strong culinary reputation.
Regent Seven Seas Cruises is the ultra-luxury, all-inclusive brand, with fares that fold in shore excursions, specialty dining, drinks, and gratuities.

Who owns MSC Cruises?

MSC Cruises is privately owned by the Aponte family through Mediterranean Shipping Company, a Geneva-based shipping group. It has no public stock and no corporate parent above it.

The story starts with Gianluigi Aponte, an Italian ship captain who founded Mediterranean Shipping Company in 1970 as a cargo business. It grew into one of the largest container shipping lines in the world, and the family later built the passenger arm to bring that maritime expertise to cruising. It remains family-controlled.

The “is it Italian?” question has a two-part answer. The founder and the brand’s dining and style are strongly Italian, but the parent is headquartered in Geneva, Switzerland, and the line operates worldwide with a heavy Mediterranean presence.

Private ownership has real effects. There is no quarterly shareholder pressure, which has allowed rapid fleet expansion and investment in private destinations, and MSC is known for low fares and frequent promotions. You also cannot buy shares of MSC Cruises the way you can with Carnival, Royal Caribbean, or Norwegian’s parent. MSC also offers a Yacht Club ship-within-a-ship product on its larger vessels. Check msccruises.com for the current fleet. For a head-to-head, see our MSC vs Norwegian comparison.

What does MSC stand for?

MSC stands for Mediterranean Shipping Company, the name of the Geneva-based, family-owned shipping group that owns MSC Cruises. The cruise line carries the initials of its much larger parent, a global cargo business founded in 1970.

Mediterranean Shipping Company began hauling containers across the world’s oceans. When it expanded into passenger travel, it kept the recognizable initials. The “Mediterranean” reflects the company’s origins and the cruise line’s strong presence in that sea, not a limit on where it sails.

It helps to keep the two arms straight:

MSC (Mediterranean Shipping Company): the parent, a container and cargo shipping group.
MSC Cruises: the passenger brand under that umbrella, carrying vacationers instead of freight.

People get confused because the cruise brand is usually marketed as just “MSC,” many travelers do not realize it belongs to one of the world’s biggest cargo shippers, and the Italian founder plus the Mediterranean name suggests an Italian company when the headquarters is in Switzerland.

Who owns Norwegian Cruise Line?

Norwegian Cruise Line is owned by Norwegian Cruise Line Holdings, a publicly traded company headquartered in Miami, Florida. Despite the name, it is a U.S.-based business. The same parent owns Oceania Cruises and Regent Seven Seas Cruises, which together with Norwegian make up the three brands of NCLH, one of the three big publicly traded cruise corporations alongside Carnival Corporation and Royal Caribbean Group.

The “Norwegian” name is a legacy. The brand began in 1966 as Norwegian Caribbean Line, founded by Norwegian shipping interests sailing from Miami. Over the decades the company changed hands and restructured, and the business, headquarters, and stock listing are now in the United States. NCLH went public in 2013.

What that means for cruisers: three brands under one roof pool buying power, technology, and loyalty infrastructure. If you start with Norwegian and want something more upscale later, Oceania and Regent are natural step-ups within the same family. And as a public company, NCLH reports results and fleet plans openly, which makes its direction easy to follow. See ncl.com for the line itself.

The independent lines

Several major lines operate without a big corporate parent.

MSC Cruises is covered above.
Disney Cruise Line is owned by The Walt Disney Company and is among the most family-oriented lines at sea, with strong kids’ clubs, character experiences, and stage-show entertainment. It runs private Bahamas islands for its ships. See disneycruise.disney.go.com.
Viking grew from a river cruise specialist into a respected ocean line for culturally curious adults. Its ocean ships are 18 and over, with no casino and an emphasis on destinations. It is independent of the three big groups.
Windstar runs small sailing yachts and motor yachts that reach ports large ships cannot.

Biggest cruise lines in the world, ranked

“Biggest” can mean ship count, passenger capacity, gross tonnage, passengers carried or revenue. The fairest single measure is capacity in lower berths, which counts two guests per cabin. That is the figure the companies report to investors, so the rankings below use it. Figures are from each company’s most recent annual report: fiscal 2025, which ended November 30, 2025 for Carnival Corporation and December 31, 2025 for Royal Caribbean Group and Norwegian Cruise Line Holdings. Fleets change as ships are delivered and retired, so treat counts as a snapshot.

The biggest cruise brands by capacity

Royal Caribbean International: 29 ships, about 111,000 berths (Royal Caribbean Group 10-K). It also has the biggest ships. Icon of the Seas, Star of the Seas, Utopia of the Seas and Wonder of the Seas each list around 5,600 to 5,700 berths in the same filing. Royal Caribbean ship tracker
Carnival Cruise Line: 29 ships, 94,340 berths, 35% of Carnival Corporation’s capacity (Carnival Corporation 10-K). It ties Royal Caribbean on ship count, but its ships are smaller on average. Carnival cruise ship tracker
MSC Cruises: 23 ships after it took delivery of MSC World America in 2025 (MSC Cruises). MSC is privately held and does not publish a fleet berth total. It ranks third here on ship count and ship size: its World-class ships are among the largest afloat. MSC ship tracker
Princess Cruises: 17 ships, 54,890 berths (Carnival Corporation 10-K).
Norwegian Cruise Line: the largest of NCLH’s three brands, which together run 34 ships with about 71,400 berths (NCLH 10-K). Norwegian ship tracker
Celebrity Cruises: 15 ships, about 38,900 berths (Royal Caribbean Group 10-K).
AIDA Cruises: 11 ships, 32,270 berths, the biggest German-market line (Carnival Corporation 10-K).
Costa Cruises: 9 ships, 31,140 berths (Carnival Corporation 10-K).
P&O Cruises (UK): 7 ships, 24,300 berths (Carnival Corporation 10-K).
Holland America Line: 11 ships, 23,030 berths (Carnival Corporation 10-K).

Smaller but well known: Cunard runs 4 ships with 9,770 berths, Seabourn 6 ships with 2,640 berths (Carnival Corporation 10-K), and Silversea 12 ships with about 5,500 berths (Royal Caribbean Group 10-K). Disney Cruise Line’s fleet reached eight ships with Disney Adventure (The Walt Disney Company). Viking had 12 ocean ships at the end of 2025, alongside 89 river vessels and 2 expedition ships (Viking 20-F).

The biggest cruise companies

Carnival Corporation: 94 ships, 272,380 berths, and 13.6 million guests carried in fiscal 2025 (10-K).
Royal Caribbean Group: 69 ships and about 179,720 berths counting its joint-venture partner brands TUI Cruises and Hapag-Lloyd Cruises, and 9.4 million guests carried in 2025 (10-K). Its three wholly owned brands, Royal Caribbean, Celebrity and Silversea, account for 56 of those ships.
Norwegian Cruise Line Holdings: 34 ships, about 71,400 berths, and just under 3.0 million guests carried in 2025 (10-K).

MSC Cruises belongs in this group too, with 23 ships under the privately held MSC Group, but it publishes no annual report, so there is no audited berth or passenger figure to rank it by. Carnival Corporation’s 10-K names Royal Caribbean Group, NCLH and MSC as its principal competitors and says the four together hold about 80% of industry capacity.

For scale: CLIA counts 37.2 million ocean cruise passengers worldwide in 2025, and its member lines operate 327 ocean ships with about 692,000 lower berths in 2026 (CLIA State of the Cruise Industry). Carnival Corporation alone carried more than a third of those passengers.

What size means for you. A bigger fleet means more home ports and itineraries, so you can often find a Carnival or Royal Caribbean sailing within driving distance. Bigger ships carry more amenities, which suits you if onboard variety matters. Large lines also run the deepest promotions, such as kids-sail-free and drink-package bundles. Smaller lines like Disney concentrate on fewer home ports, which can mean flying to your cruise.

How the industry consolidated. The big-three structure came from decades of deals. Carnival Cruise Line began in 1972 and acquired Holland America Line in 1989. Disney Cruise Line launched in 1997. Carnival and P&O Princess merged in the early 2000s. Norwegian changed hands several times before NCLH went public in 2013. Royal Caribbean later took control of Silversea, and MSC accelerated its building program. The pandemic halted operations in 2020, and demand rebounded strongly afterward.

Does parent-company ownership affect your experience?

Mostly no. Each brand runs its own ships, crew, menus, and culture, and a Princess cruise and a Carnival cruise feel nothing alike despite a shared parent. A few things do cross brands: some loyalty recognition between sister lines, shared purchasing and logistics at the corporate level, and common safety and training standards. Loyalty points, onboard credit, pricing, and the day-to-day experience do not carry across.
