In the typology of ancient Greek pottery, the kernos (Greek κέρνος or κέρχνος, plural kernoi) is a pottery ring or stone tray to which are attached several small vessels for holding offerings. Its unusual design is described in literary sources, which also list the ritual ingredients it might contain. The kernos was used primarily in the cults of Demeter and Kore, and of Cybele and Attis.
The Greek term is sometimes applied to similar compound vessels from other cultures found in the Mediterranean, the Levant, Mesopotamia, and South Asia.
