Trinwillershagen was founded in the 14th century during the German Ostsiedlung (colonisation of the East). Its name is derived from the Old High German "Tründel", the name for the round shaped type of settlement that is called Rundling. Maps dating from 1583 show the round or circular shape of the village with small ponds in its middle.
After the GDR had been founded and following the land reform, the Landwirtschaftliche Produktionsgenossenschaft (LPG) Trinwillershagen "Rotes Banner" was founded, which was dismantled only after the German reunification in 1991. During the 1990s some new family homes have been built and old houses have undergone diligent restoration work. Much of the former LPG area has been turned into meadows and park land.
Trinwillershagen is situated between Stralsund (to the East) and Ribnitz-Damgarten (about 10 km to the West). On an area of 34,21 km² there are 1.377 inhabitants (June 2005).
Walter Ulbricht and Anastas Mikoyan, member of the Soviet Politburo, visited the LPG and the village in 1957 in order to see the "modern socialist" farming industry that had been installed there. On July 13, 2006, George W. Bush, President of the United States, visited Trinwillershagen during a state visit, as Trinwillershagen is located in Chancellor Angela Merkel's home district.
