The Battle of Malta took place on 8 July 1283 in the entrance to the Grand Harbour, the principal harbour of Malta, as part of the War of the Sicilian Vespers. An Aragonese fleet of galleys, commanded by Roger of Lauria, attacked and defeated a fleet of Angevin galleys commanded by Guillaume Cornut and Bartholom Bonvin.The Angevin ships arrived in Malta first, and proceeded to relieve the Angevin garrison, which was besieged within the walls of the Castello del Mare. The galleys were followed in close pursuit by an Aragonese fleet. Roger of Lauria easily out-maneuvered the Angevin-Provenal fleet, and destroyed almost all of Cornut and Bonvin's vessels. Lauria then sailed back northwards, making a demonstration off Naples, raided the neighbouring coast, attacked and then garrisoned Capri and Ischia. The crushing defeat forced Charles I of Naples to postpone his plan to invade Sicily.

Roger of Lauria (c. 1245 – 17 January 1305) was a Neapolitan admiral in Aragonese service, who was the commander of the fleet of the Crown of Aragon during the War of the Sicilian Vespers. He was probably the most successful and talented naval tactician of the Middle Ages. He is known as Ruggero or Ruggiero di Lauria in Italian and Roger de Llúria in Catalan.
