Meaning and history
Colter developed from an English occupational surname for a keeper of horses, derived from the Middle English word colt. Its use as a given name is comparatively modern and reflects the popularity of surnames as first names. Historical frontiersman John Colter helped make the surname familiar, while singer-songwriter Colter Wall is a notable modern bearer.
Colter rose from #218 to #157 for boys between 2024 and 2025. That year also produced its highest recorded birth count, at 2,354.
