Tyberius is an ancient Roman name of Etruscan origin, derived from the Etruscan god Tibertus who was worshipped at the Tiber River. The name is composed of two elements: 'tif' meaning twin and 'baris' meaning youth. Therefore, Tyberius can be interpreted to mean 'youthful twins'. In Roman history, the most famous bearer of this name was Emperor Tiberius Claudius Nero (42 BC – 37 AD), who succeeded Augustus as emperor of the Roman Empire. The name was also used among other notable Romans, including Tiberius Sempronius Gracchus and Tiberius Coruncanius, both of whom were consuls during the early Roman Republic. In modern times, Tyberius has been a popular choice for baby boys in some European countries, particularly Germany and Poland, where it ranks among the top 500 names.
The name Tyberius has seen fluctuating popularity over the years, with a notable increase from 2014 onwards, reaching its peak in 2017 and 2018 before declining slightly in recent years.
