Antoine Ferrein (October 25, 1693 – February 28, 1769) was a French anatomist who was a native of Frespech, which today is a commune in the arrondissement of Villeneuve-sur-Lot.
He was a professor at the Collège Royal in Paris, and in 1742 became a member of the Académie des sciences.
He postulated that the ligaments of the larynx were analogous to the cords on a violin.
He also made the correlation between the size of the glottis and the loudness of a person's voice.
There are several anatomical eponyms attributed to Antoine Ferrein, including: Grmek, M.D.
