Denison is English in Origin.

Denison is an English patronymic name meaning “son of Denis/Denys,” with Denis deriving from Latin Dionysius, ultimately Greek Dionysios, “follower of Dionysus.” Veneration of the third‑century martyr St. Denis helped spread the base name across medieval France and, via the Normans, into England, giving rise to surnames built on Denis and its variants.

As a given name, Denison emerged from the English-speaking custom of adopting family surnames as first names, most visible in 18th–19th‑century Britain and North America. It remains uncommon yet familiar through its link to Dennis. Spelling variants and related patronymics include Dennison, Denyson, and Denson; the root forms are Denis (French, Slavic), Dennis (English), and Denys (medieval/Scots). Short forms such as Den and Denny occur, while feminine cognates include Denise and Denisa. Denison lends a tailored, traditional feel with classical roots and a subtle saintly association.
