Louis Alexandre Mangin (8 September 1852 in Paris – 27 January 1937) was a French botanist and mycologist. In 1873 he became an associate professor at the Lycée de Nancy, followed by a professorship at the Lycée Louis-le-Grand in Paris (1881–1904).
During this time frame, he was also a lecturer on natural sciences at the Sorbonne (from 1890).
From 1904 to 1931 he was a professor (Chaire de cryptogamie) at the Muséum national d'histoire naturelle, and was director of the museum from 1919 until his retirement in 1931.
For several years he was director of the menagerie at the Jardin des Plantes (1920 to 1926). Mangin was a member of the Académie des sciences, the Académie d'agriculture de France, the Académie des sciences coloniales and the Société mycologique de France. His early research dealt largely with plant anatomy and physiology; his doctoral thesis involving the adventitious roots of monocotyledons.
With Gaston Bonnier (1853–1922), he performed extensive research of plant respiration, transpiration and carbon assimilation.
In the early 1890s he is credited with the discovery of callose, a fundamental substance found in the cell membrane of plants.
