Opus /ˈoʊpəs/ (Ancient Greek: Ὀποῦς, romanized: Opoûs or Ὀπόεις) was an ancient Greek city that was the chief city of a tribe of Locri, who were called from this place the Opuntian Locrians, and the territory, the Opuntian Locris.

It was located on the coast of mainland Greece opposite Euboea, perhaps at modern Atalanti. Its harbor was at Kynos. It stood at the head of the Opuntian Gulf, a little inland, being 15 stadia from the shore according to Strabo, or only a mile according to Livy. Opus was believed to be one of the most ancient towns in Greece. Pindar's ninth Olympian ode concerns Opus. It was said to have been founded by Opus, a son of Locrus and Protogeneia; and in its neighbourhood Deucalion and Pyrrha were reported to have resided. It was the native city of Patroclus, and it is mentioned in the Homeric Catalogue of Ships as one of the Locrian towns whose troops were led by Ajax the Lesser, son of Oileus the king of Locris, in the Iliad There were games called Aiantea and an altar at Opus in honor of Ajax.
