Collby Origin and Meaning

The name Collby is a boy's name.

Collby is a variant spelling of the more common name Colby, which originated as an English surname derived from places containing the Old Norse elements 'kol' (coal, charcoal) and 'byr' (farm, settlement). As a first name, Collby emerged in the late 20th century as part of the trend toward using surnames as given names. The alternative spelling with double 'l' gives the name a slightly distinctive touch while maintaining the friendly, approachable sound of the original. Though less common than Colby, Collby shares the same sporty, contemporary feel that appeals to parents seeking a modern masculine name with historical roots but without being overly traditional.
