Junia (feminine, Greek: Ιουνια), or Junias (masculine, Greek: Ιουνιας), along with Andronicus, were "kinsmen and fellow prisons" of Paul. They were held in high esteem and were believers in Christ. In his letter to the Romans, Paul asked the Christians of Rome to greet Junia(s) and Andronicus.

Greet Andronicus and Junias, my kinsmen and [once] my fellow prisoners, who are held in high esteem in the estimation of the apostles, and who were [believers] in Christ before me.

— Romans 16:7 (AMP)
