Sicilian nationalism, or Sicilianism, is a movement in the autonomous Italian region of Sicily, as well as the Sicilian diaspora, which seeks greater autonomy or outright independence from Italy, and/or promotes further inclusion of the Sicilian identity, culture, history, and linguistic variety.

The flag of Sicily shows a triskeles symbol, and at its center a Gorgoneion with a pair of wings and three wheat ears. In the original flag, the wheat ears did not exist and the colors were reversed. The original flag was created in 1282 during the rebellion of the Sicilian Vespers.
