MS Estonia was a cruiseferry built in 1980 for the Finnish shipping company Rederi Ab Sally by Meyer Werft, in Papenburg, West Germany. She was employed on ferry routes between Finland and Sweden by various companies until the end of January 1993, when she was sold to Nordström & Thulin for use on Estline's Tallinn–Stockholm route. The ship's sinking on 28 September 1994, in the Baltic Sea between Sweden, Finland and Estonia, was one of the worst peacetime maritime disasters of the 20th century, claiming 852 lives.
