Kellis is a unisex given name that blends Irish and classical Latin influences. As a modern variant of Kelley—itself from the Gaelic O’Ceileachair, meaning “companionable”—Kellis also evokes the Latin word caelis (“heavens”), lending it a subtle classical resonance. Pronounced KEH-lis (/ˈkɛlɪs/), the name has appeared in U.S. newborn records since 2001, with annual occurrences ranging from five to sixteen and Social Security rankings between 896 and 975. Its concise, gender-neutral form and cross-cultural roots make Kellis an appealing choice for parents seeking a distinctive name that honors both Celtic heritage and Latin tradition.
