Meaning & origin

Alli is a concise and friendly name that has been in use since 1916. While never reaching the top tiers of popularity, it saw its peak year in 2011, when it was most frequently chosen. Since then, its trajectory has been falling. In 2025, about one in 89,293 girls were named Alli, making it a relatively rare choice. The name is often used as a nickname for longer names like Allison or Alice, but it has also stood on its own. Alli did not have any top states associated with it, indicating a scattered usage across the country. Despite its simplicity, the name carries a sense of approachability and charm.

Alli is most commonly a short form or variant of Alison, itself a Norman French diminutive of Alice. Alice derives from the Old French name Aalis, a form of the Germanic name Adalheidis, meaning 'noble' or 'of noble kind.' In modern times, Alli has been used as an independent given name, particularly in the United States.
