Marianowo [marjaˈnɔvɔ] is a village in Stargard County, West Pomeranian Voivodeship, in north-western Poland.

The area became part of the emerging Polish state under its first historic ruler Mieszko I around 967.

The origins of the village go back to the foundation of Cistercian monastery in 1228 by Duke Barnim I the Good of Pomerania from the Griffin dynasty.

[4] On 28 June 1643 Gustavus Adolphus' daughter, Christina of Sweden, leased the estates of Marienfließ nunnery to Francis Henry of Saxe-Lauenburg for 10 years, after which it reverted to the new ruler of Pomerania, Frederick William, the Great elector, on 12 December 1653, rewarding Francis Henry's improvements to the estate.

[5] Under Brandenburg rule the damsels' foundation was restituted, but dissolved in 1945, when Marienfließ was handed over to Poland.
