Henri Lucien Jumelle (25 November 1866 in Dreux, Eure-et-Loir Department, France – 6 December 1935 in Marseille, Bouches-du-Rhône Department, France) was a French botanist.^[1]

From 1887 to 1894, he worked as a plant physiologist at the Faculté des Sciences in Paris. Afterwards, he was a professor of botany at the Faculté des Sciences in Marseille (1894-1935).^[2] From 1898 to 1916, he was assistant director, then director of the Musée colonial et du Jardin botanique in Marseille.^[3]

He held a deep interest in applied botany, publishing numerous treatises on the agricultural aspects of various plants.^[4] During his career, he worked closely with botanist Joseph Alfred Perrier de la Bâthie, who sent him botanical material from Madagascar. As a taxonomist, he circumscribed many new species native to Madagascar.^[2]

From 1922 to 1935, he was a correspondent-member of the Académie des Sciences (botanical section).^[3]
