Haydyn is a modern respelling of Hayden or Haydn, names that have competing origins. The surname Haydn (as in the composer Joseph Haydn) is German, derived from the personal name Hadu, meaning "battle" or "strife." Hayden as an English surname may come from various place names, such as Haydon in Dorset, meaning "hay hill." The use of Haydyn as a given name emerged in the late 20th century, likely influenced by the popularity of similar-sounding names like Aiden and Jayden.
