The Spanish–Portuguese War (1762–1763) was fought as part of the Seven Years' War. The first theatre of the war was an invasion of Portugal by Spain in alliance with France against the Anglo-Portuguese Alliance, which ended in disaster after three defeated invasion attempts. The second theatre was a Spanish invasion of Portuguese colonies in South America, which ended in stalemate.

Because no major battles were fought, even though there were numerous movements of troops and heavy losses among the Spanish invaders, this theatre of the Seven Years' War is known in Portuguese historiography as the Fantastic War (Portuguese and Spanish: Guerra Fantástica).

The war ended along with the Seven Years' War in the 1763 Treaty of Paris.
