Oceania Cruises is a Miami, Florida, United States-based shipping company that operates six premium cruise ships on worldwide itineraries. The sixth ship, formerly "Ocean Princess" and renamed "Sirena", joined the fleet in 2016. 
Since September 2014, Oceania Cruises has been owned by Norwegian Cruise Line Holdings, LTD. which also owns Norwegian Cruise Line (NCL) and Regent Seven Seas Cruises. While it also offers cruises as short as ten days, the norm is 10- to 14-days and the line is also known for its long cruises lasting up to 180 days. The line's president and ceo is Bob Binder, he is vice-chairman and also a co-founder of the brand.
Oceania Cruises was founded in 2002 by luxury cruise industry veterans Frank Del Rio, Bob Binder, and Joe Watters. The founding management team also included industry veterans Robin Lindsay, James Rodriguez, Jeff Drew, and Howard Sherman.
The company chartered the former Renaissance Cruises ship R Two from Cruiseinvest and renamed her Insignia in October 2002. In April 2003 the Insignia was chartered to the French travel agency TRM for three months, during which Oceania Cruises operated no vessels. On 15 June 2003 Oceania Cruises re-commenced service with two ships: the Insignia was renamed Regatta and a new ship (R One, a sister ship of the Insignia/Regatta, also chartered from Cruiseinvest) entered service as the new Insignia.
In November 2005, a third R-class ship entered service for Oceania Cruises when the company chartered the R Five from Cruiseinvest and renamed her Nautica. At the naming ceremony of the Nautica, Frank del Rio announced the plan of adding a fourth ship, Marina, to the Oceania Cruises fleet in July 2007. This however did not come to pass.
In February 2007, the majority of Oceania Cruises' stock were sold to the New York-based Apollo Management. The following month Oceania made a memorandum agreement with the Fincantieri shipyard in Italy to construct two new 1,250-passenger ships. The contract was finalised in June 2007, with delivery dates for the new Oceania Class ships set for January 2011 and July 2011. The contract also includes an option for a third vessel of the same type that could be delivered in May 2012, but Oceania declined the option.
After being leased out for two years to Hapag-Lloyd as the Columbus 2, the Insignia returned to the fleet in 2014.
In May 2014 it was announced that Oceania and Fincantieri are close to making a deal on two additional ships for the Oceania Class. The order for these additional ships never came to pass.
On November 25, 2014, Norwegian Cruise Line Holdings Ltd announced a definitive agreement with Princess Cruises to purchase the Ocean Princess for Oceania Cruises, upon delivery in March 2016, the ship underwent a 35-day, $40 million refurbishment in Marseille, France to become the Sirena.
The Regatta class ships were built in 1998--2000 for Renaissance Cruises as a part of their R class. They have a gross tonnage of 30,277 and can accommodate a maximum of 824 passengers in 343 cabins.
