The Italo-Normans (), or Siculo-Normans ("Siculo-Normanni") when referring to Sicily and Southern Italy, are the Italian-born descendants of the first Norman conquerors to travel to southern Italy in the first half of the eleventh century. While maintaining much of their distinctly Norman piety and customs of war, they were shaped by the diversity of southern Italy, by the cultures and customs of the Greeks, Lombards, and Arabs in Sicily.
