Meaning & origin

Infinity first appeared in U.S. birth records in 1993 and reached its peak popularity in 1997, with a rank of 4,661 in 2025. Currently, the name is given to roughly 1 in every 55,423 newborns. Its trajectory has been rising since 2012, reflecting a modern taste for abstract, conceptual names. Though not concentrated in any single state, Infinity's appeal spans a wide range of families drawn to its philosophical and cosmic resonance. As a word name, it fits alongside other aspirational choices like Nova and Serenity, offering a sense of boundlessness and potential.

Infinity is derived from the English word 'infinity,' itself from Latin 'infinitas' (unbounded). It has been used as a given name since the 1990s, likely influenced by abstract virtue names and a trend toward word names. Its rise in use coincides with a broader cultural fascination with concepts of boundlessness and cosmic themes.
