William Edward Gumbleton (2 March 1840 – 4 April 1911) was an Irish horticulturist with at least one species (Arctotis gumbletonii) and two cultivars named after him.

William Edward Gumbleton was educated at Brasenose College, Oxford, where he matriculated 8 June 1858, but seems to have left the university before graduating, as there is no record of his being awarded a degree.

There, he devoted himself to horticulture, specialising in the growing of rare and newly introduced plants, particularly the species and cultivars of the Compositae such as Dahlia, Gnaphalium, Arctotis and Olearia.

There are examples of cases where, during visits to other people's gardens, he destroyed inferior specimens of plants, sometimes with his umbrella.

Hooker, "in tardy recognition of Mr. Gumbleton's services as a raiser and flowerer of many fine new plants".
