MS Ocean Endeavour is a cruise ship. She operated as Konstantin Simonov in the Baltic sea from construction, undergoing a refit in 1988. From 1996 to 2001, the ship operated as Francesca in the Mediterranean sea. Until 2010, the ship was owned by Israeli Mano Cruise (after a refit in 2001) and operated in the eastern Mediterranean sea under the name The Iris, during which time it was registered in Malta. The ship was refitted again and joined Kristina Cruises as Kristina Katarina in late 2010, taking over as flagship from the much smaller Kristina Regina. On 8 January 2014, the ship was sold and renamed Ocean Endeavour.
She is currently being operated in the northern summer season on the east coast of Canada, Greenland and the Canadian Arctic; by Adventure Canada and in the southern summer season to Antarctica from Ushuaia; by a joint venture between Peregrine Travel and Chimu Adventures  Adventure Canada is an independent, family-owned expedition cruise company from Mississauga, Ontario, Canada. Chimu Adventures and Peregrine are Australian owned Adventure travel companies.
