Jean Nicolas Bréon (27 September 1785, Sierck – 1864, Noyon), often known as Nicolas Bréon, was a noted French plant collector and botanist.
From 1809 he worked as a student gardener at the Muséum national d'histoire naturelle in Paris, later serving as a botanist/gardener at the botanical garden in Ajaccio (1813).
In February 1815 he was named a gardener-botanist of the French Navy.
During his time on Réunion, he organized several botanical trips to Madagascar, the Maldives and the Arabian Peninsula.
[1][2] The genus Breonia was named in his honor by botanist Achille Richard — the genus Breonadia (family Rubiaceae) is most likely named after him.
