About Kuiper
Kuiper is the Dutch form of Cooper ("barrel maker"), but it may be more prominently associated with the Kuiper Belt, a band of small space rocks near Neptune where many comets are believed to come from. As a surname, it was notably borne by astronomer Gerard Kuiper, while as a first name, it made its debut to the US stats in 2025.
Kuiper for girls
It might appeal to those who love Piper and Kaia, who enjoy last-names-as-first-names, and who want a space-related name.
Kuiper for boys
While this may be the Dutch version of Cooper, English-speaking parents are likely to choose this with reference to the Kuiper Belt, a band of small space rocks near Neptune thought to be where many comets come from. With Kai or Ky as potential cool nicknames, this is one underused name with a lot to offer.
Pronounced KY-pur.
As of October 2026, Kuiper ranked #9460 in US births in 2024 SSA, peaked at #4633 in 2022.
