Philippe-Isidore Picot de Lapeyrouse or La Peirouse, Baron de Lapeyrouse (20 October 1744 in Toulouse – 18 October 1818 in château de Lapeyrouse, Haute-Garonne) was a French naturalist.
He was particularly interested in the flora and fauna of the Pyrenees.[2] After the revolution, he became the first professor of natural history in Toulouse and his collections, from 1796, were housed in the former Carmelite Monastery of Toulouse which went on to become the Muséum de l'Histoire Naturelle de Toulouse.[3]
