Meaning & Origin
Kianu is a boy's baby name, likely a variant of Keanu, a Hawaiian name meaning "the cool breeze" or "cool mountain breeze." Hawaiian names have a distinctive musicality — every syllable is a vowel or vowel-consonant pair, giving names like Keanu their flowing, open-air quality.
Keanu became globally recognized through actor Keanu Reeves, who has carried the name with quiet cool for decades. Kianu takes that same beautiful Hawaiian root and offers an alternate spelling that's equally melodic. For families with Hawaiian heritage or simply a love of this name's breezy, nature-rooted meaning, Kianu is a lovely choice.
