Tiberius Claudius Nero (c. 85 - 33 BC) was a member of the Claudian Family of ancient Rome. He was a descedant of Tiberius Claudius Pius Felix Nero who was Roman Consul in 202 BC through his father Drusus Claudius Nero. His mother was a descendant of the first Appius Claudius Pulcher. His family were republicans.

He was the father of the Roman Emperor Tiberius and the general Nero Claudius Drusus; grandfather to Germanicus, Drusus Julius Caesar, Livilla and the Roman Emperor Claudius; great-grandfather to Emperor Caligula; and great- great-grandfather to Nero.

After he served as quaestor, he commanded Caesar's fleet in the Alexandrian War. When he won the victory, Caesar awarded him as a priest and encouraged to create Roman colonies in Gaul and in other provinces.

He created an amnesty for senators to avoid quarrelling among themselves after Caesar's death. Later he was elected praetor. Tiberius was a supporter of Caesar and Mark Antony, but not of Octavian.

In 43 BC or 42 BC, he married his relative Livia Drusilla in Rome. His son of the same name was born 16 November 42 BC, at Fondi, Italy. After 3 years of fleeing from Octavian he returned to Rome with his wife (who was pregnant) and the younger Tiberius, aged 3.

Octavian fell in love with his wife. On the day that Tiberius and Livia were divorced, she married Octavian. Their second son was born in Lyons, France in January 38 BC. His name was Nero Claudius Drusus.

Drusus was returned to him several months later. Tiberius raised and educated his sons. He died in 33 BC. His sons went to live with their mother and stepfather. The younger Tiberius delivered his funeral eulogy.

In Tiberius' coming of age, he staged 2 gladiatorial contests, one at the Forum and other at the amphithreatre, in memory of his father and grandfather.
