Kolby Origin and Meaning

The name Kolby is a girl's name.

Kolby as a feminine name represents a gender-crossover trend in naming practices. Traditionally used for boys as a variant of Colby (derived from Old Norse elements meaning 'dark farm' or from English place names referring to 'coal town' or 'Koli's settlement'), its adoption for girls reflects the modern tendency to repurpose surnames and masculine names for feminine use. The spelling with 'K' instead of 'C' adds a contemporary twist to the traditional form. While still predominantly used for boys, Kolby has gained some traction as a girl's name among parents seeking gender-neutral options with a modern edge. The name carries a sturdy, practical sound with a friendly 'by' ending that softens its overall impression.
