The Celtic meaning of Kian is "Ancient." The Persian meaning of Kian is "King" or "Royal". This can be found on BtN name database under the Iranian name Kianoush which is the Persian form of Kian.

I find the name Kian a very refreshing sound. I love the meaning of the name. Kian is currently one of my favorite boy names.
