Kylon is a modern American name that extends Kyle, the Scottish place name meaning "narrow strait" or "channel", with the -on ending of Kylan and Dylan. It happens to match the ancient Greek Kylon, an Athenian nobleman of the 7th century BC, but the modern name is not derived from him. Kylon peaked at number 2,143 in 2003 and ranks number 2,699 among boys in 2025, with 48 births.
