Tosi

Tosi is an Italian surname borne by many individuals of Italian descent. The name is commonly found in Italy and among Italian communities abroad. The precise etymology is not definitively established in standard references; surnames like Tosi are often considered of Italian origin and may be derived from a given name, a diminutive, or a toponym, with regional variations in spelling and usage.

Notable individuals with the surname include Piero Tosi (1929–2019), an Italian costume designer whose long career spanned cinema and theatre. He was recognized for his collaborations with major directors and for creating period and character costumes that contributed to the visual identity of numerous productions.

Beyond this, the surname appears across a range of professions, including arts, academia, and public life, without a single figure universally identified as representative of the name. As with many Italian surnames, Tosi can be encountered in historical records, genealogical research, and contemporary directories, reflecting the dispersion of Italian families through migration and diaspora.
