Meaning & origin
Kadyn first appeared in U.S. birth records in 1994, a relatively recent addition to the American naming landscape. By 2009, it reached its peak rank, a year when the name was at its highest usage. Since then, its popularity has been falling, and in 2025 it ranked 2991st, given to roughly 1 in every 41660 newborns. The name has been most popular in Pennsylvania and Florida, reflecting regional preferences for modern, phonetically crafted names. Kadyn is part of a wave of -aden names that surged in the late 1990s and 2000s, though it has never achieved the widespread adoption of closely related forms like Caden or Kayden.
Kadyn is a variant of the modern name Caden, which first appeared in the United States in the 1990s. Its origins are uncertain; it may be derived from the Irish surname Caden, an Anglicized form of Mac Cadáin 'son of Cadán', or it may be an invented name influenced by the popular -aden suffix seen in names like Aiden and Jayden. Kadyn has been used for both boys and girls since its first recorded use in 1994.
