Meaning & origin

Lyonel is a rare medieval variant of Lionel that saw its peak popularity in the United States in 2023 before beginning a slight decline. In 2025, it ranked 12,008th with approximately 1 in 341,615 newborn boys receiving the name. Its trajectory has been falling since 2022, indicating a shift away from this spelling. The name first appeared in U.S. records in 1925, and despite its long history, it has never achieved widespread use. Lyonel appeals to parents seeking a traditional yet uncommon name with strong sound and Arthurian resonance.

Lyonel is a Medieval English and French variant of Lionel, derived from the Latin 'leo' meaning lion, with the diminutive suffix '-el' to mean 'little lion'. The name was popularized in Arthurian legend and later used as a given name in England from the Middle Ages onward. It experienced a revival in the 19th century alongside other medieval names.
