The Spanish–Portuguese War (1762–1763) was fought as part of the Seven Years' War. The first and main theatre of the war was an invasion of Portugal by Spain in alliance with France against the Anglo-Portuguese Alliance, which ended after three disastrous invasions. The second theatre was a Spanish invasion of Portuguese colonies in South America. Though tactically successful for the Spanish in the strategically important area on and near the River Plate, their gains there were largely given up in the peace negotiations, resulting in a strategic success for the Portuguese in South America.

Because no major battles were fought in the Portuguese segment of the war, even though there were numerous movements of troops and heavy losses among the Franco-Spanish invaders, this theatre of the Seven Years' War is known in Portuguese historiography as the Fantastic War (Portuguese and Spanish: Guerra Fantástica) in the sense of phantom war, due to the successful Portuguese strategy of starving the invading Franco-Spanish army of supplies while avoiding or minimising pitched battles.

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