Meaning & origin
Sky is a nature name that first appeared on U.S. records in 1958, reaching its peak popularity in 2021. In 2025 it ranked 948th, given to about 1 in 5,909 babies. The name has seen a steady rise in use, particularly in states like Connecticut, Utah, and Louisiana, and has shown a slight decline since 2022. As a modern word name, Sky lacks deep historical roots but benefits from its airy, open-ended quality. Its simplicity and gender-neutral appeal continue to attract parents looking for a name that feels both contemporary and connected to the natural world.
Sky derives from Old Norse 'ský' meaning 'cloud', adopted into Middle English as 'sky' referring to the heavens. It emerged as a given name in the 20th century, part of a trend for nature and word names. Its use has grown steadily since the 1960s, particularly in the United States, and it remains popular among parents seeking a simple, unisex name.
