Meaning & origin

Tiberius is a Roman imperial name that has never entered widespread American use, but maintains a steady, modest presence. The Social Security Administration first recorded the name in 1992, and its peak popularity came in 2017. As of 2025, the name ranks 3128th, with approximately 1 in every 45,000 newborn boys receiving the name. The name has been on a slight downward trajectory since 2016, but it remains a recognizable and historically weighty choice for parents drawn to classical Roman nomenclature.

Tiberius is a Latin praenomen (given name) of uncertain etymology, thought to be connected to the Tiber River (Latin Tiberis). The name was famously borne by the second Roman Emperor, Tiberius Claudius Nero, who reigned from 14 to 37 CE. Though it declined after antiquity, it was revived during the Renaissance and has seen occasional use in the modern era, particularly among classicists and in historical fiction.
