The Locrians are an ancient Greek tribe in Greece.

The Locrians speak the Locrian dialect, a Doric-Northwest dialect, which indicates that they may have been relatives of the Dorians.

They inhabit the ancient region of Locris in Central Greece.The prehistoric residents of Locris were Leleges, who were replaced by Locrians when the Greek tribes started to arrive in southern Greece.

However, Dionysius of Halicarnassus does not separate them, mentioning that Locrians is the later name of the Leleges, in the way other ancient historians identify Hellenes with the peoples who preceded them in Greece.

Aristotle and other writers supposed the name of the Locrians to be derived from Locrus, an ancient king of the Leleges.

According to some traditions, Deucalion, the founder of the Hellenic race, is said to have lived in the Locrian town of Opus or Cynus.
