Dr. Agustín Stahl (January 21, 1842 – July 12, 1917) was a Puerto Rican medical doctor and scientist with diverse interests in the fields of ethnology, botany, and zoology. He advocated Puerto Rico's independence from Spain.

Stahl was born in Aguadilla, Puerto Rico and given the name Antón Adolf August, by his parents Johann Heinrich Christian Stahl and María Helene Stamm. Born into a Protestant family, he was baptized into the Catholic faith in Aguadilla at about three years of age, town where he also received his primary and secondary education.

He studied at the universities of Würzburg and Prague (at the Charles University), graduating from the latter with the title of Doctor of Medicine in 1864. After graduation, Stahl returned to Puerto Rico where he established his medical practice in the city of Bayamón.

Outside work, Stahl's love of nature lead him to conduct investigations and experiments in the fields of ethnology, botany and zoology. He also had a love of history and historical investigation.

Stahl wrote "Estudios sobre la flora de Puerto Rico" (A study of the Puerto Rican Flora), published in 6 fascicles from 1883-88. Copies of Stahl's plant collection with approximately 1,330 plants can be found in various botanical gardens around the world. His collections were the basis for numerous studies by specialists, some of them resulting in new taxa to science.

Stahl has a genus, Stahlia, and five valid species, Argythamnia stahlii, Senna pendula var. stahlii , Eugenia stahlii, Lyonia stahlii, and Ternstroemia stahlii, named in his honor. The genus Stahlia is represented by a single species, S. monosperma (Tul.) Urb., known to occur only in Puerto Rico and the eastern Dominican Republic. Known in Puerto Rico as Cóbana Negra, this species is currently listed as threatened in the USFW Federal Register, April 5, 1990.
