The Northern Seven Years' War (also known as the Nordic Seven Years' War, the First Northern War or the Seven Years War in Scandinavia) is the war between Sweden and a coalition of Denmark-Norway, Lubeck and Polish-Lithuanian Commonwealth, fought between 1563 and 1570.

The fighting continues until both armies have been exhausted, and many men die.

The resulting peace is a stalemate, with neither party gaining any new territory.
