Kos Surname Meaning

The Greek surname Kos (Κως or Κός) is a toponymic surname derived from geographic origin rather than personal characteristics. It refers to the island of Kos in the Dodecanese and was historically used to identify individuals who originated from the island and later settled elsewhere in Greece or abroad. Such geographic identifiers were especially common during periods of migration, trade, or resettlement, when newcomers were distinguished by place of origin. Over time, these identifiers became fixed family names passed down through generations, even when direct ties to the island diminished. Consequently, the surname Kos signifies “the one from Kos” or “the family originating from the island of Kos,” reflecting ancestral geographic identity.
