Olympias (Greek: Ὀλυμπιάς) was a wealthy Christian Roman noblewoman of Greek descent who lived in the second half of the 4th century and first half of the 5th century.

One of the parents of Olympias, was the sibling to the great Christian Saint Olympias. Olympias had one sibling, a brother called Seleucus, who served as a Praetorian prefect in the Theodosian dynasty.

Olympias is the known granddaughter of the Antiochian noblewoman Alexandra and her husband, the wealthy Rhetor Seleucus. Unfortunately little is known of the life of Olympias.
