RMS Carinthia was an ocean liner built in 1956 as one of the four Saxonia class ships. She sailed for Cunard Line from her completion until 1968 when she was sold to Sitmar Line. Upon her sale she was rebuilt into a full-time cruise ship and renamed SS Fairsea.
She sailed with Sitmar until 1988, at which time Sitmar was sold to P&O. She was renamed SS Fair Princess and sailed for P&O Cruises (and their subsidiary Princess Cruises) until 2000. She was then sold to China Sea Cruises and renamed SS China Sea Discovery.
In 2006 she was scrapped in Alang, India.
