Jules Pierre Fourreau (25 August 1844, Lyon – 16 January 1871, Beaune) was a French botanist.
As a young man he worked as an assistant to botanist Alexis Jordan (1814-1897) in Lyon. Beginning in the mid-1860s, he began collecting plants throughout southeastern France (Ardèche, the Alps, Provence, et al.). In November 1870 he enlisted in the Légionnaires du Rhône, and on 16 January 1871 he died in a hospital in Beaune as a result of injuries received at the Bataille de Nuits (18 December 1870).
In 1864 he became a member of the Société linnéenne de Lyon. In 1867 he introduced the genus name Mistralia (family Thymelaeaceae) in honor of poet Frédéric Mistral. In 1869 he founded the Société de la Renaissance, serving as its first president.
The genus Fourraea (family Brassicaceae) is named in his honor.
