The Angevin invasion of Sicily (1298–1302) was a military campaign launched against the Kingdom of Sicily by an alliance of the Angevin Kingdom of Naples, the Crown of Aragon, and the papacy during the War of the Sicilian Vespers. Fought in the final years of the 20-year long war, the campaign saw the alliance make some territorial gains on the island before ultimately withdrawing in the face of Sicilian resistance.

Marked by sieges, guerilla warfare, and engagements at sea, the invasion saw the Angevin–Aragonese–Papal allies engage in operations to seize control over major cities in Sicily, with varying degrees of success. However, controlling the Sicilian interior proved to be difficult, and allied control was only consistently established in northeast and southeast Sicily. The failure of the final allied offensive in 1302 directly led to the signing of the Peace of Caltabellotta, the treaty that concluded the War of the Sicilian Vespers.
