Meaning & origin

Kroi is a modern name that first entered U.S. birth records in 2019, a time when short, distinctive names ending in 'y' or 'i' were fashionable. It reached a rank of 4,539 in 2025, its peak year so far, with an incidence of about 1 in 77,640 births. The name has shown consistent upward momentum, reflecting a taste for novel, sleek-sounding names that fit contemporary naming patterns. Its geographical footprint is narrow, appearing most frequently in New York, suggesting an urban, trend-sensitive origin. While its exact derivation is uncertain, Kroi likely belongs to a class of invented or creatively respelled names, similar to Jax or Kace, rather than stemming from a long historical tradition. The lack of known variants or nicknames underscores its status as a very recent addition to the baby name landscape.

Kroi first appeared in U.S. records in 2019. It may be a respelling of Croix, the French word for 'cross,' or a creative variation of names like Troy or Kroy. Its sudden rise suggests a modern coinage rather than a traditional name.
