The aryepiglottic muscle is an intrinsic muscle of the throat.

The muscle originates from the muscular process of arytenoid cartilage and inserts to the aryepiglottic crease and lateral boundary of epiglottis. Aryepiglottic muscle is innervated by the inferior laryngeal nerve, a division of the recurrent laryngeal nerve (a division of the vagus nerve). The muscle adducts arytenoid cartilages and serves as a sphincter on laryngeal inlet.
