Jean-Henri Humbert (24 January 1887 – 20 October 1967) was a French botanist born in Paris.
He studied physics, chemistry and natural sciences in Rennes and Paris, and following a scientific excursion to Madagascar, he worked as a university assistant at the faculty of Clermont-Ferrand (from 1913).
In 1931 he succeeded Henri Lecomte (1856-1934) as chair of botany at the Muséum national d'histoire naturelle in Paris.
Humbert was a member of the Académie des sciences d'outre-mer (1938) and the Société botanique de France, serving as its president from 1940 to 1944.
He has a handful of botanical genera named after him, including Humbertiella from the tribe Hibisceae.
