Adolphe Boucard (1839 – 15 March 1905) was a French ornithologist who collected extensively in Mexico and Central America. He concentrated on collecting hummingbirds and sold scientific bird skins to Natural History museums and supplied the plume trade. He published the periodical The Hummingbird (1891–95). He spent his later years in England on the Isle of Wight and died at his son's home in Hampstead.
Species named after Boucard include Boucard’s Tinamou Crypturellus boucardi (also known as Slaty-breasted Tinamou) assigned in 1859 by Philip Sclater.
