MS Moby Dada is a cruiseferry operated by Moby Lines under charter from DFDS Seaways on a service connecting Helsinki, Finland to St. Petersburg, Russia. She was built in 1981 as Finlandia for Effoa at Wärtsilä's Perno shipyard in Turku, Finland, and placed in service on Silja Line's Helsinki— service. In 1990 she was sold to DFDS Seaways and renamed Queen of Scandinavia. She entered service under her the name of Princess Maria and operated for St Peter Line in 2010.

In 2016, following the purchase of St Peter Line by Moby Lines, Princess Maria was renamed Moby Dada on the 10th November 2016 and was transferred to the Italian flag of registry, she completed her last sailing with St Peter Line on the 8th November and will transfer to Moby Lines in the Mediterranean.

Originally to be named Skandia,Finlandia was the first large, modern cruiseferry to be built for Silja Line. At the time she was also the world's largest cruiseferry in terms of passenger capacity, beds and volume. Alongside her sister MS Silvia Regina (and Viking Line's contemporary Viking Saga and Viking Song) she was instrumental in changing the Helsinki-Stockholm route from a transportation service into a cruise route.

Finlandia and Silvia Regina were originally constructed with very 'fat', curving bows to maximise car-carrying capacity, but these made the ship extremely difficult to handle especially during the winter. As a result, the Finlandia was docked in January 1982 (after just eight months of service) in Wärtsilä's Perno shipyard for reconstruction of her bow to a sleeker form. Following the bow reconstruction additional rebuilding was done at Wärtsilä's Turku shipyard, where additional cabins were built and repairs were carried out on the restaurants.
