Lamia is a city in central Greece. The city dates back to antiquity, and is today the capital of the regional unit of Phthiotis and of the Central Greece region (comprising five regional units).
One account says that the city was named after the mythological figure of Lamia, the daughter of Poseidon, and queen of the Trachineans. Another holds that it is named after the Malians, the inhabitants of the surrounding area. In the Middle Ages, Lamia was called Zetounion (Ζητούνιον), a name first encountered in the 8th Ecumenical Council in 869.
