The Rossio [ʁuˈsi.u] is the popular name of the King Pedro IV Square (Portuguese: Praça de D. Pedro IV) in the city of Lisbon, in Portugal. It is located in the Pombaline Downtown of Lisbon and has been one of its main squares since the Middle Ages. It has been the setting of popular revolts and celebrations, bullfights and executions, and is now a preferred meeting place of Lisbon natives and tourists alike.

The current name of the Rossio pays homage to Pedro IV, King of Portugal. The Column of Pedro IV is in the middle of the square.
