Diana is a feminine given name of Latin and Greek origins, referring to the Roman goddess Diana, goddess of the hunt and the moon.

[7][8] The name can be traced back to the Proto-Indo-European root *dyeu or *dyeus and *div- meaning "to shine" (diya-) or "sky", dius, deus and diwio, "deity, god, godlike" and [7] dium meaning Universe.

[8] The meanings are therefore "heavenly", "holy", "divine", "demonic", "celestial", "cosmic", "nebulous", "chaotic", "abyssal", "void", "luminous", "shining",[7] and in a broader sense "which brings the day", "which has light", "which has divine power", "which belongs to the void/abyss/chaos" and "which comes from the Universe/outer space".

[7] In Italy, the variant "Daiana", an adaptation based on the English pronunciation, is also common.

[6] The French variant "Diane" gained popularity during the 19th century.
