Kyren is a modern American name of uncertain origin, usually explained as a respelling of Kieran, the Irish name that means "little dark one", or as a blend of the popular Ky- sound with names like Darren and Kyrie. It fits the pattern of short, two-syllable boys' names ending in -en. Kyren hovered around number 1100 for most of the 2010s, broke into the top 1000 in 2023 and reached number 584 in 2025, its highest rank yet.
