Meaning & Origin
a male given name, equivalent to English Marcellus
Marcello is a boy's and girl's baby name of Italian origin, the Italian form of Marcellus, from the Latin diminutive of Marcus — connected to Mars, the god of war — meaning "little Marcus" or "young warrior." It has been a classical Italian name since Roman antiquity.
Italian actor Marcello Mastroianni — the archetypal Italian film star of the 1960s and 1970s — made this name synonymous with Mediterranean charisma and romantic sophistication. In the United States, Marcello has grown as parents discover Italian names beyond Marco and Mario.
