The Mecklenburg Spa Railway (German: Mecklenburgische Bäderbahn) is a non-electrified, single track branch line in the north of the German state of Mecklenburg-Vorpommern. It runs from Rövershagen, east of the Hanseatic city of Rostock, to Graal-Müritz on the Baltic coast. Its name came originally from the name of its operator and was later transferred to the line.
