Meaning & origin

Lylith is a rare, modern name whose exact origins are unclear. It first appeared in U.S. birth records in 1918, but remained obscure for most of the 20th century. Since 2007, the name has been on a steady upward trajectory, reaching its peak rank of 7491 in 2025. It is currently given to roughly 1 in every 114,805 baby girls, reflecting a modest but growing appeal among parents seeking distinctive, feminine names. Lylith has not been heavily concentrated in any particular state or region, remaining a scattered choice across the country. Its sound evokes both the floral Lily and the mythic Lillith, though no single etymological source is universally accepted. The name's rarity and melodic quality contribute to its increasing, though still niche, popularity.

Lylith is a modern coinage, possibly combining elements of Lily (derived from the flower name) and Lillith (a Hebrew name meaning 'night' or 'night creature'). It first appeared in limited use in the early 20th century, with sporadic records from 1918 onward. The name gained slow but steady traction in the 21st century, particularly after 2007, as parents increasingly favored unique, melodic names ending in '-ith' or '-yth'.
