Kyah is a modern spelling of Kya and Kaia, short names of mixed origin that are usually linked to the Hawaiian kai, "sea", or to Kaia as a Scandinavian pet form of Katherine, "pure". The -ah ending gives it a softer look in the style of Leah and Micah. In the United States Kyah peaked at number 1221 in 2002 and ranks at number 2876 in 2025.
