Meaning & origin
Cadie is an uncommon and modern American name that first appeared in official records in 1978. It reached its peak popularity in 2005, though even then it was rare; that year, it ranked among lower tiers of the Social Security data. Since 2008, its frequency has been steadily declining, and by 2025 it was given to approximately 1 in every 321,453 newborn girls, placing it at rank 14,942. The name's spelling likely reflects a modern trend of substituting -ie for -y, giving a softer, more feminine feel. While its exact meaning is unclear, it is most commonly understood as a variant of Katie or Cady, both of which are themselves diminutives or respellings with probable roots in Catherine. Cadie has not been recorded in any top state lists, suggesting its use is scattered rather than regionally concentrated. Parents drawn to Cadie often also consider similar-sounding names like Sadie, Katie, and Callie. The name carries a friendly, approachable sound that fits well with current preferences for short, -ie-ending girl names.
Cadie is a modern English name, likely a respelling or variation of Katie (a diminutive of Catherine, from Greek Aikaterinē, meaning 'pure' or debated) or Cady (itself possibly from Irish surname Ó Cáida meaning 'descendant of Cáide', or an English nickname). The spelling 'Cadie' emerged in the late 20th century, influenced by the trend of -ie endings for girls' names, and has seen sporadic use in the United States since the late 1970s.
