Aristides Agramonte y Simoni (June 3, 1868 – August 19, 1931) was a Cuban American physician, pathologist and bacteriologist with expertise in tropical medicine. In 1898 George Miller Sternberg appointed him as an Acting Assistant Surgeon in the U.S. Army and sent him to Cuba to study a yellow fever outbreak. He later served on the Yellow Fever Commission, a U.S. Army Commission led by Walter Reed which examined the transmission of yellow fever.
