Keahu is Hawaiian in Origin.

Keahu is a Hawaiian given name pronounced keh-AH-hoo. It combines the article ke, “the,” with ʻahu, a noun meaning altar, shrine, cairn, or pile; by extension, ʻahu also denotes a cloak or garment, as in the famed ʻahuʻula (feather cape). The name therefore carries senses such as “the sacred altar,” “the cairn,” or figuratively, “the mantle (of rank/protection).” It is used for all genders in Hawaiian contexts.

Found in 19th‑century Hawaiian Kingdom records and surviving in modern use, Keahu remains uncommon outside Hawaiʻi. Orthographically careful forms include Keʻahu (showing the glottal stop) and the spaced Ke Ahu; simple Keahu is frequent in English contexts. Related or elaborated forms include Ahu, Keahuokalani (“the altar of the heavens/sky”), and compounds referencing ʻahuʻula. A contemporary bearer is the American actor Keahu Kahuanui, which has helped introduce the name beyond the Islands. Variant spellings with diacritics are recommended when honoring Hawaiian language norms.
