What is Hera's Roman name?

The Roman equivalent of Hera was the goddess Juno. She was the goddess of marriage and childbirth as well as the patron goddess of the Roman Empire.

Juno took on many roles in Roman society, and the Romans gave her a number of epithets to reflect this multiplicity of roles. For example, Juno Sospita was the protector and patron of the Roman state, Juno Regina ruled as queen of the gods, Juno Curitis protected spearmen, and Juno Lucina looked after women in childbirth. The first day of each month, known as the kalends, was sacred to Juno. Juno often appeared in the company of a peacock.
