Cassiano Conzatti (1862 – 1947) was an Italian‑born botanist, horticulturist, and naturalist who spent the majority of his professional career in Mexico. He is noted for his extensive field work documenting the flora of the Mexican highlands, his role in the development of botanical gardens in the country, and for publishing several influential botanical texts.
