The Thirty Years' War in Eastern Europe refers to the wider impact of the Thirty Years' War on regions outside the main areas of conflict in Germany and Central Europe.

The extent to which the Thirty Years' War can be seen as a single event occurring within coherent geographical boundaries has long been discussed by historians. While not directly involved, countries and regions outside the main areas of conflict were also affected, and in some respects, the war can therefore be seen as a Pan-European event.

Events in Eastern Europe were driven by a mixture of anti-Habsburg sentiment, strategic concerns, opportunism, religion, economics, and dynastic rivalry. These were often exploited for diplomatic advantage by outside powers, including Sweden, the Dutch Republic, France, Austria, Spain, and the Ottoman Empire.
