Junia Lepida (Classical Latin: IVNIA•LEPIDA, PIR2 I 861, ca 18 - 65) was a Roman noble woman that lived during the Roman Empire in the 1st century. Lepida was the second born daughter and was among the children born of Aemilia Lepida and Marcus Junius Silanus Torquatus, a member of the Junii Silani, a family of Ancient Rome. Her maternal grandparents were Julia the Younger (granddaughter of the emperor Augustus) and Lucius Aemilius Paullus (a consul). Through her maternal grandparents she was a descendant of Roman emperor Augustus, noble woman Scribonia, statesman Marcus Vipsanius Agrippa and consul Lucius Aemilius Lepidus Paullus (brother of the triumvir Marcus Aemilius Lepidus).
She married Gaius Cassius Longinus (ca 13 BC - 69). Cassius was a person with remarkable ancestral wealth. They raised their nephew Lucius Junius Silanus Torquatus, whose father was murdered by Empress Agrippina the Younger. In 66, Lepida's husband and nephew were expelled from Rome by Emperor Nero for being a part in Gaius Calpurnius Piso's conspiracy. Cassius was deported to Sardinia. Lepida was accused by Nero of black magic and incest with her nephew. Her fate afterwards is not known. Lepida's husband was Praefectus urbi Romae ca 27, Consul suffectus in 30, Proconsul Asiae in 40 or 41, Legatus Augusti pro praetore provinciae Syriae between ca 45 and 49 and was later rehabilitated and recalled from exile by Vespasian.
Lepida bore Longinus two children:
- Cassia Longina (b. ca 35), married to Roman General Gnaeus Domitius Corbulo by whom she had two daughters Domitia and Domitia Longina
- Cassius Lepidus (b. ca 55), married to an unknown woman by whom he had a daughter Cassia Lepida (b. ca 80). She married Gaius Julius Alexander Berenicianus (b. ca 80), Consul in 116 and Proconsul Asiae in 132, and had a daughter - Julia Cassia (a great-great-great-great-great granddaughter of Augustus)
