Norman Humbert Joy (7 July 1874 – 20 January 1953) was a British ornithologist and coleopterist.
Joy's beetle collection is held at the British Entomological and Natural History Society headquarters at Dinton Pastures Country Park, Berkshire.
Some beetle specimens collected by Joy from the Berkshire area are held at the Museum of Reading.
In addition to his work on Coleoptera, Joy also discovered the Brown Ant Lasius brunneus (then unknown in Britain) at Theale in Berkshire on 21 January 1923 (Donisthorpe 1927).
The Berkshire Birds website credits him as discovering the ornithological potential of Reading Sewage Farm.
