Josiah Gregg (19 July 1806 – 25 February 1850) was an American merchant, explorer, naturalist, and author of Commerce of the Prairies, about the American Southwest and parts of northern Mexico. He collected many previously undescribed plants on his merchant trips and during the Mexican–American War, for which he has often been credited in botanical nomenclature.
