Lucius is a masculine given name derived from Lucius (Latin [ˈluː.ki.us]; Etruscan: Luvcie), abbreviated L., one of the small group of common Latin forenames (praenomina) found in the culture of ancient Rome. Lucius probably derives from Latin word lux (gen. lucis), meaning "light" (<PIE *leuk-, "brightness"), related to the Latin verb lucere ("to shine") and cognate to the name Lucas. Another proposed etymology is derivation from Etruscan Lauchum (or Lauchme) meaning "king", which was more directly transferred into Latin as Lucumo.
Lucia and Lucy are feminine forms of the name.
In addition, Lucius is a British masculine given name and an Austrian, German, Luxembourgish and Dutch surname. Lucius has been translated into Italian, Spanish and Portuguese, as Lucio. Derived from the related patronymic Lucianus is Luciano in Italian, Spanish and Portuguese, Lucien in French and Luken in Basque.
