Jean-Baptiste Barla (3 May 1817, Nice – 6 November 1896) was a French botanist.
Barla was a man of independent means and dedicated himself to investigate the fungi and orchids of the South of France. "Cette végétation exceptionelle, doit évidemment sa richesse et sa variété à la configuration topographique, toute particulière, du bassin des Alpes-Maritimes. Dans ce pays favorisé par la nature, croissent la plupart des orchidées de France, d'Italie, d'Allemange, etc." (Introduction to illustrée de Nice et des Alpes-Maritimes).
In 1846 with Jean Baptiste Vérany (1800–1865) he founded the Muséum d'histoire naturelle de Nice where wax casts of thousands of mushrooms he made or had made were exhibited.
