Tropea is a municipality in the province of Vibo Valentia, in Calabria, southern Italy.

Tropea is a seaside resort with sandy beaches, located on the Gulf of Saint Euphemia, part of the Tyrrhenian Sea, on Italy's west coast.

A legend suggests that the town was founded by Hercules when returning from his labours at the Pillars of Hercules (the modern-day Strait of Gibraltar). Graves of Magna Graecian origin have been found near Tropea.

Along Tropea's coast, Sextus Pompey defeated Octavius. The Romans built a commercial port in Formicoli, approximately 3 km south of Tropea.

Villages around Tropea produce red onions that are well-known in Italy. Cipolle di Tropea ("Tropea onions") have become a synonym in Italy for all red onions.
