Emmelia of Caesarea (Greek: Ἐμμέλεια) was born in the late third to early fourth century, a period in time when Christianity was becoming more widespread, posing a challenge to the Roman government and its pagan rule.

Her daughter Theosebia the Deaconess is honoured as a saint in Eastern Orthodoxy but only as a blessed in the Catholic Church.

Emmelia spent much of her later years living with her eldest daughter, Macrina the Younger.

With her husband no longer around, Emmelia and her daughter lived a life dedicated to Christianity, surrounded by servants whom they treated as equals, at Macrina the Younger's insistence.

Their ascetic way of life attracted a following of women which created a convent-like atmosphere, where one was considered rich if she lived a pure and devout Christian life and disregarded the materialistic lure of earthly pleasures and possessions.
