Ruby Princess is a Crown-class cruise ship operated by Princess Cruises, a subsidiary of Carnival Corporation & plc. At 113,561 GT, the vessel is the third and last in a series of three ships, known as the Crown class, that was built with design modifications distinguishing them from their older Grand-class sister ships. Delivered in 2008 by Italian shipbuilder Fincantieri, Ruby Princess also became the ninth and final Grand-class ship to join the Princess Cruises fleet.
