Kia is a mononym originating from Hawaiian, meaning 'the ultimate one'. It has gained popularity as a unisex given name in recent years.
"Kia appears to have been a popular baby name for girls from the late 1970s to the mid-1990s, with peaks in 1989 (12 births) and 1993 (13 births). However, it has seen a significant decline since then, with only five births each year from 2005 onwards. As of 2023, the total number of births with the name Kia stands at 190."
