Coressia or Korissia (Ancient Greek: Κορησσία),[2] also spelt Coresia or Koresia (Κορησία),[3] also known as Coressus[4] and Arsinoe (Ἀρσινόη),[3][5] was a town of Ceos,[5] and functioned as the harbour of Iulis.

Near it was a temple of Apollo Smintheus, and the small stream Elixus flowed by it into the sea.

There are a very few remains of the town on the heights upon the west side of the bay.

The site of Coressia is located near modern Livadi,[5][3] which wa renamed to Korisia in 1922.
