Ko (Korean: ; Hanja: 髙; 高), also variously romanized Go, Goh, or Koh, is a common Korean surname.

Among Koreans with this surname, the largest clan is the Jeju Go clan, named for its bon-gwan (clan hometown) of Jeju Island; they claim descent from Go Eul-na, the first ruler of the kingdom of Tamna, which ruled Jeju until being absorbed by the Joseon dynasty.
