The Aronson Prize (German: Aronson-Preis) is a prize awarded for achievements in microbiology and immunology. It was established by the will of the pediatrician and bacteriologist Hans Aronson and has been awarded since 1921. Aronson bequeathed a large part of his estate to the establishment of the prize. The prize is awarded biannually on 8 March, the date of Aronson's death. The first laureate was August von Wassermann. Among the Aronson laureates are several scientists who later were awarded the Nobel Prize in Physiology or Medicine, such as Karl Landsteiner and Gerhard Domagk.
