Tulio is an Italian masculine given name, derived from the Latin word 'tullius', which means "of Tusculum". This name has been used historically and remains popular among families of Italian origin. It was notably borne by several prominent figures throughout history, such as Cicero's friend and fellow philosopher Marcus Tullius Tiro.
Tulio had periods of popularity with peaks in the late 1980s and mid-2000s. However, it has been less common recently, with only six to ten births per year since 2016.
