Meaning & origin

Colbey is a rare respelling of the more common Colby, a name that originated as an English surname and place name. Its peak year of usage was 2002, after which its popularity has steadily declined. The name first appeared in U.S. records in 1983, but it has never been common enough to rank in the national Top 1000. Parents drawn to the -ey ending may prefer this variation for its distinctive spelling. Like many surname-derived first names, Colbey feels casual and approachable.

Colbey is a variant of the surname Colby, which comes from an English place name meaning either 'Koli's settlement' (from Old Norse personal name Koli) or 'coal town' (from Old English col 'coal' and by 'farm, settlement'). The surname has been used as a given name in the United States since the late 20th century, with the respelling Colbey being far less common than Colby.
