Adolph Albrecht Erlenmeyer (11 July 1822 – 9 August 1877) was a German physician and psychiatrist born in Wiesbaden. He studied medicine in Marburg, Bonn and Berlin. At the University of Bonn he studied under surgeon Karl Wilhelm Wutzer (1789–1863), and after receiving his doctorate from the University of Berlin, he was an assistant to psychiatrist Carl Wigand Maximilian Jacobi (1777–1858) at the asylum in Siegburg. As a young man, Erlenmeyer was influenced by Jacobi's somatic approach to psychiatry, and felt that there needed to be a close unity of psychiatry and neurology.
