Dea is a unisex given name of Latin origin, meaning "goddess" or "divine." It is often used as a shortened form of various female names such as Déirdre, Deidra, or Deandra, but can also stand alone as an independent name. In some cultures, Dea is associated with the Roman goddess of fertility and abundance, which may influence its interpretation and usage.
"The name Dea experienced limited popularity in the early to mid-20th century with a total of 17 births recorded over two periods, peaking at 6 births each in 1921 and 1925 before dropping to 5 in 1980."
