Hermann Friedrich Teichmeyer (30 April 1685 – 5 February 1746) was a German physician and botanist born in Hannoversch Münden. He was father-in-law to Albrecht von Haller (1708–1777).

The botanical genus Teichmeyeria (Scop., 1777) is likely named after him, although etymological information is lacking.^[1] It is considered to be synonymous with the genus Gustavia.^[2]

Teichmeyer was a professor of experimental physics, medicine and botany at the University of Jena. He was a pioneer of forensic medicine, being remembered for his 1723 publication of Institutiones medicinae legalis vel forensis, an important textbook on forensics that was later translated into German.
