Tiberius Claudius Caesar Augustus Germanicus (August 1 10 BC – October 13 54) (Tiberius Claudius Drusus Nero Germanicus before his accession) was the fourth Roman Emperor of the Julio-Claudian dynasty, ruling from January 24 41 to his death in 54. Born in Lugdunum in Gaul (modern-day Lyon, France), to Drusus and Antonia Minor, he was the first Roman Emperor to be born outside Italy.

The gens Claudia was one of the oldest families in ancient Rome, and for centuries its members were regularly leaders of the city and empire.
