Auguste François Le Jolis (1 December 1823, Cherbourg - 20 August 1904, Cherbourg) was a French merchant, judge and botanist.
He is largely known for investigations of cryptogams (algae, hepatics, mosses) found in the department of Manche. In August 1852, he was a founding member of the Société Nationale des Sciences Naturelles et Mathématiques de Cherbourg.
The algae genus Lejolisia was named after Le Jolis by Jean-Baptiste Édouard Bornet (1828-1911).
