Glen is a Scottish name from the Gaelic gleann and means "valley" or "narrow valley", the landscape word behind Glencoe and Glenfiddich. It was a solid mid-century American name, worn by the country star Glen Campbell, and the spelling Glenn has usually been the more common one. In the United States Glen ranked number 765 in 2000, left the top 1000 soon after and stands at number 2026 in 2025 with 74 births.
