Thalna is an Etruscan Goddess of childbirth. Her name is related to the Greek root thal- ("flowering" or "flowery"), from which comes the prettiest name in the whole world, "Thalia". Thalna's name probably relates to the idea of things blossoming or coming into being, and to springtime, newness, and beginnings—certainly applicible to a Goddess of midwives and the process of birth. She may also be a Goddess of light, much like Lucina, an aspect of Juno Who helped babies to be born forth into the light of day.

Thalna is shown on many Etruscan mirror-backs, which were commonly engraved with mythological scenes. She is often depicted with fellow midwife Goddesses Thanr and Ethausva helping the God Tinia (Jupiter or Zeus) "give birth" to Menrfa (Minerva or Athene) from his head, from which the war Goddess springs fully armed. One mirror shows Her helping Tinia again "give birth", this time to Fufluns (Etruscan Dionysos) from His thigh. Thalna can be shown supporting Tinia from behind, Her arms around His chest to steady Him, or simply in attendance at the miraculous births.

Thalna is sometimes called the wife or consort of Tinia, and may be a springtime aspect of the Goddess Cupra, said by Strabo to be the Tyrrhenian (Etruscan) name for Hera (or Juno, Queen of the Gods) in Umbria. Thalna, like Thanr and Ethausva (or Menrfa for that matter), is sometimes shown with great wings. She can be richly dressed or nude save for jewelry, but She is invariably young and beautiful.
