The Derby di Sicilia (English language: Sicilian Derby) is a local derby between Italian football clubs Calcio Catania and U.S. Città di Palermo. Catania and Palermo are the two main cities on the island of Sicily, and the teams are fierce rivals. However, they have seldom played each other within the Italian football league system, because in many seasons they have played in separate divisions of the league. The first time the Sicilian derby took place in the context of league football was on November 1, 1936, at Palermo in Serie B level; it ended in a 1–1 draw. The Sicilian derby has been played 10 times in Serie A: Catania leading their rivals by 5 victories to Palermo's 4; the other occasion was drawn. The teams have also met in local Sicilian competitions, and friendly matches.
