Jean-Claude Delamétherie (also de La Métherie, de Lamétherie, 4 September 1743 – 1 July 1817) was a French naturalist, mineralogist, geologist and paleontologist. He edited Journal de physique, de chimie, d'histoire naturelle et des arts from 1785. He was elected member of Leopoldina in 1792. He was a supporter of the French Revolution, but opposed to the Jacobins, and was forced to leave Paris during the Reign of Terror, interrupting publication of the Journal de physique until 1797. Numerous minerals were first systematically described by Delamétherie. In 1795, Delamétherie first described the Lherzolite (which he named after the site of its discovery,  Étang de Lers in the Pyrenees).
