Stacy

Stacy is a girl's and boy's baby name of Greek origin, a variant of Stacey, which developed as a diminutive of the medieval name Eustace, from the Greek Eustakhios meaning 'fruitful' or 'productive.'

Stacy hit peak popularity in the 1970s, part of a wave of breezy, casual names that felt distinctly modern for that era. While less common as a new baby name today, it carries the cheerful energy of its generation and works well as a middle name or nod to a family namesake.
