Tartaras is a commune in the Loire department in central France. It is in the Gier valley just north of the river, between Rive-de-Gier to the west and Saint-Romain-en-Gier to the east.


The village dates back to the Roman era. Gallo-Roman sarcophagi are still visible in the town. During the 19th century Tartarus was in the heart of a coal basin.
