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.

Ferrein is remembered for his work involving the physiology of voice, and is credited for coining the term cordes vocales ( vocal cords). 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:

• "Ferrein's canal": (rivus lacrimalis); A space between the eyelids when closed and the eyeball through which tears flow to the lacrimal punctum.
• "Ferrein's foramen": Hiatus of facial canal that makes passage for the greater petrosal nerve.
• "Ferrein's ligament": The thickened external portion of the capsule of the temporomandibular joint.
• "Ferrein's pyramid": Also known as the medullary ray, which is the center of the renal lobule, and is shaped like a small pyramid.
• "Ferrein's vasa aberrantia": Aberrant biliary canaliculi that have no connectivity with hepatic lobules.
