Boud.

Jean Louis Émile Boudier (6 January 1828, Garnay – 4 February 1920, Blois) was a pharmacist who lived in Montmorency, France. He published a fair amount about the Discomycetes and other areas of mycology. He often used Émile as his first name.

He received his education at the École de Pharmacie de Paris, and in 1853, established a pharmacy in Enghien-les-Bains. He then became manager of his father's pharmacy, where he worked for many years. In 1878 he retired as a pharmacist in order to devote his time to scientific research.

He was a founding member of the Société mycologique de France (vice-president 1884; president 1887–90) and an honorary member of the British Mycological Society.

He named several species including Amanita franchetii, Disciotis venosa, Ptychoverpa bohemica, and Trichoglossum hirsutum.
