Pierre André Pourret (1754–1818) was a French abbot and botanist who did research and teaching in France and Spain.
Pourret was also a pioneer user of binomial nomenclature, first developed by Carl Linnaeus.
Pierre André Pourret was a clergyman, but started his botanical career earlier, working in the regions around his hometown, Narbonne.
He sent manuscripts of documented research to the Académie des sciences, inscriptions et belles-lettres de Toulouse.
Due to xenophobia to the French during Napoleon's invasion of Spain, an angry mob drove Pourret out of his herbarium, burning many of his resources in the process.
