Julia Minor or the Younger (Classical Latin: IVLIA•MINOR, 19 BC-28 or early 29) was the eldest daughter of Marcus Vipsanius Agrippa and Julia the Elder and as such Emperor Augustus' granddaughter through her mother). Agrippina the Elder (Germanicus' wife) was her younger sister. Vipsania Agrippina (Tiberius' and later Gaius Asinius Gallus' wife), also a daughter of Marcus Vipsanius Agrippa, was their half-sister.

About 5 BC or 6 BC, Augustus arranged her to marry Lucius Aemilius Paullus (consul 1). Paullus had a family relation to her as her first half-cousin, as both had Scribonia as grandmother: Julia's mother was a daughter of Scribonia by Augustus; Paullus' mother, Cornelia Scipio, was a daughter of Scribonia resulting from her earlier marriage to Publius Cornelius Scipio Salvito.

Paullus and Julia had a daughter, Aemilia Lepida and son Marcus Aemilius Lepidus. According to Suetonius, she built a large pretentious country house. Augustus disliked large overdone houses and had it demolished.

In 8, Julia was exiled for having an affair with Decimus Silanus, a senator. She was sent to Trimerus, a small Italian island, where she gave birth to a child. Augustus rejected the infant and ordered it to be exposed, or left on a mountainside to die. Silanus went into voluntary exile, but returned under Tiberius' reign.

In 14, her husband Paullus was executed as a conspirator in a revolt. Livia Drusilla plotted against her step-daughter's family and ruined them. This led to open compassion for the fallen family. Julia died on the same island where she had been sent in exile twenty years earlier. Due to the adultery that Julia committed, Augustus stated in his will that she would never be buried in Rome.. She was survived by her son and daughter and by several grandchildren.

Julia Agrippina is also mentioned under following names: * Vipsania Julia (Agrippina); * Iulilla; * Julia, Augustus' granddaughter * Julia (Caesaris) minor. She was not Julia Caesaris by birth: being the daughter of a Vipsanius Agrippa makes her a Vipsania Agrippina by birth, although there are no contemporary sources that show that that name would have been used for her. She came to belong to the household of the Julio-Claudian dynasty as she was raised and instructed by her maternal grandfather Augustus. Further Augustus adopted Tiberius as his son (and heir), and while Tiberius was remarried to Julia the Elder, Augustus sort of became paternal grandfather to Julia the Elder's children too, including Julia the Younger. A formal adoption "in the family of the Caesars" among the offspring of M. Vipsanius Agrippa and Julia the Elder is however only recorded regarding Vipsania Julia's brothers Gaius — hence Gaius Caesar — and Lucius — hence Lucius Caesar. Her youngest sister (Agrippina the elder) and brother (Agrippa Postumus) are usually called after their natural father. Likewise, her eldest half-sisters (Vipsania Agrippina and Vipsania Marcella) were named after their father Vipsanius (Agrippa). Her youngest half-brother, unnamed in contemporary sources, was later sometimes dubbed Tiberillus, after his father Tiberius.

Note that also the youngest of the two sisters of Julius Caesar is sometimes named Julia (Caesaris) minor by historians.
