Heydon is English in Origin.

Heydon is an English surname-turned-given name taken from several place-names in Norfolk, Cambridgeshire, and elsewhere. Its second element is Old English dūn “hill.” The first element varies by locale: hēg “enclosure/hedge” or hay, and sometimes hēah “high.” Hence meanings such as “hedged hill,” “hay hill,” or “high hill.” The -don ending distinguishes it from Hayden with -den (denu “valley”). Pronounced HAY-dən, Heydon preserves the locational flavor of medieval English toponymy.

As a forename, Heydon appears sporadically from the 19th century through the surname-name trend, gaining indirect momentum alongside the broader popularity of Hayden in the late 20th and early 21st centuries. It remains the rarer, more traditional-feeling spelling. Common variants and cognates include Haydon, Heyden, and Hayden; the name also overlaps in contemporary use with Irish Aidan/Aodhán (“little fire”) by sound, though not by origin. Nicknames may include Hey, Haze, or Don.
