Corseae or Korsiai (Ancient Greek: Κορσίαι or Κορσιαί[1]) was a port of ancient Boeotia on the Corinthian Gulf.[2] It appears from Pliny the Elder that this town was distinct from Corseia, also in the western part of Boeotia, and that it was distinguished from the other by the name of Thebae Corsicae,[3] that is the Corseae near or belonging to Thebes.
