Sirena, formerly R Four, Tahitian Princess, and Ocean Princess is an R-class cruise ship formerly owned by Princess Cruises. When part of the Princess fleet, along with the Pacific Princess, Ocean Princess was one of the two smallest in the fleet. In March 2016, she was sold to Oceania Cruises and renamed Sirena.
The vessel entered operation in 1999 under the flag of Renaissance Cruises. The ship was not owned by the company; instead she was owned by a group of French investors. When Renaissance declared bankruptcy in 2001, the ship was seized by creditors, along with the other seven vessels in the fleet.
In 2002, Princess Cruises secured a two-year lease for R Four and her sister shipR Three (now Pacific Princess). The vessel entered operation at the end of 2002, and was renamed Tahitian Princess. At the end of the lease, Princess Cruises purchased both vessels.
