Albert Gaillard (5 September 1858 in Neuilly-sur-Seine – 28 July 1903 in Angers) was a French mycologist.
From 1889 to 1903, he worked as curator of the Lloyd herbarium in Angers (later known as the "Arboretum de la Maulévrie Herbiers de la Ville d'Angers"). In 1887 he collected mycological and botanical specimens in Venezuela; mainly in the vicinity of Puerto Ayacucho and places along the Orinoco River, journeying as far as San Fernando de Atabapo. In Colombia, he collected specimens along the Rio Guaviare, a tributary of the Orinoco.
The genus Gaillardiella (family Nitschkiaceae) was named in his honor by Narcisse Théophile Patouillard (1895).
