The Toronean Gulf or Toroneos Gulf (Greek: Τορωναίος κόλπος, romanized: Toronaios Kolpos) and Toronaic Gulf (Ancient Greek: Τορωναϊκὸς κόλπος),[1] also known as the Kassandra Gulf (Greek: Κόλπος Κασσάνδρας, romanized: Kolpos Kassandras), is a gulf of the Thracian Sea, part of the northern Aegean Sea, in Chalkidiki, Greece.

[2] It lies between the Kassandra peninsula in the west,[3] and Sithonia in the east.

The harbour of Torone, the only city on the gulf, was known as the "deaf" harbour due to the gulf's quietness and calmness.

[4] The ancient city of Olynthus was said to be at the head of the Toronean Gulf.
