The Massacre of the Latins was a large-scale massacre of Italian-descent Catholics (called "Latins") in Constantinople, the capital of the Byzantine Empire, by the Eastern Orthodox population of the city in April 1182.

The Catholics of Constantinople at that time dominated the city's maritime trade and financial sector. Although precise numbers are unavailable, the bulk of the Latin community, estimated at 60,000 at the time by Eustathius of Thessalonica, was wiped out or forced to flee. The Genoese and Pisan communities especially were devastated, and some 4,000 survivors were sold as slaves to the Turkish Sultanate of Rum.

The massacre further worsened relations and increased enmity between the Western and Eastern Christian churches, and a sequence of hostilities between the two followed.
