In Ancient Greece, a metic (Greek: metoikos) was a foreigner living in a Greek city-state (polis). The metic did not have the same citizen rights as a citizen who was born in the state he was living in.

The term 'metic' was especially used in ancient Athens in the 4th and 5th centuries BC. A notable metic was Aristotle, who was born in Stageira but lived in Athens for a long time.
