MS Club Harmony is a cruise ship owned by Polaris Shipping and operated by Harmony Cruises. She was built in 1969 by the Wärtsilä Turku Shipyard in Turku, Finland as the container ship MS Axel Johnson for the Sweden-based Rederi AB Nordstjernan. In 1986 she was sold to Regency Cruises with the intention of being converted into a cruise ship under the name MS Regent Sun, but she was laid up instead. In 1987 she was sold to and renamed MS Italia but continued laid up. In 1988 the ship was acquired by Costa Cruises, renamed Costa Marina and rebuilt into a cruise ship at the T. Mariotti shipyard in Genoa, Italy. She entered service as the Costa Marina in 1990. After a refurbishment in 2002, she was marketed more towards German passengers. She was designed to blend together the outdoors with elegant Italian art.
The Costa Marina left the fleet in November 2011 and Iberocruceros' Grand Voyager will assume her position for Red Sea cruises. Costa Marina was renamed Harmony Princess and is now sailing for Korea’s Harmony Cruise. On August 3, 2011 an article was released stated of a new ship to be built for Costa and the ship will be the replacement once Costa's older ships have been sold starting with the Costa Marina.
In September 2014, she was  on her way to Alang, India, to be broken up.
