Franz Julius Ferdinand Meyen (June 28, 1804 - September 2, 1840) was a Prussian physician and botanist.
Meyen was born in Tilsit, East Prussia. In 1830 he wrote Phytotomie, the first major study of plant anatomy. Between 1830 and 1832 he took part in an expedition to South America on board the Prinzess Luise, visiting Peru and Bolivia, describing species then new to science such as the Humboldt penguin.
