Greifswald nuclear power station (German: Kernkraftwerk Greifswald, KKW Greifswald), also known as Lubmin nuclear power station, was the largest nuclear power station in East Germany before closure shortly after the German reunification.

In late 1989, nuclear regulatory bodies of countries operating VVER plants found the need to fit many new safety systems, which were stated to have been necessary in almost all areas.

Convinced that upgrading to the new safety standards was not economically feasible, the new unified German government decided in early 1991 to decommission the four active units, close unit 5, which was under test at the time, and halt construction of the rest of the units there plus two VVER-1000s at the Stendal Nuclear Power Plant.

Decommissioning of units 1 through 5 began in 1995, making Greifswald one of the first nuclear power stations in Germany to go through the process.

At its peak, the plant employed around 10,000 full-time workers; around 1,000 are working on decommissioning and other activities at the site.
