Claudia Julia Livilla Minor (September 18-42 AD) was the youngest child of Agrippina the Elder and Germanicus. She was mainly raised by her mother, the Emperor Tiberius, his mother Livia Drusilla and her grandmother Antonia Minor. She was born on the Greek Island of Lesbos (leading Robert Graves to refer to her as "Lesbia" in his I, Claudius and Claudius the God.)

In 33, she married Marcus Vinicius. Vinicius' family came from a small town outside of Rome. He descended from a family of knights and his father and grandfather were consuls. Her husband was mild in character and was an elaborate orator. Vinicius was appointed by Tiberius as a commissioner in early 37.

In 39, she was exiled by her brother Caligula for an attempt to overthrow him. After he was killed, she returned from exile. Later in 41, she fell out of favour with Messalina and was charged by her uncle Claudius with adultery with the historian Seneca.

Both were exiled. In 42, her uncle ordered her execution, without a defence and on unsupported charges.
