In human anatomy, the hypopharynx (or laryngopharynx) is the bottom part of the pharynx, and is the part of the throat that connects to the esophagus.

The superior boundary of the hypopharynx is at the level of the hyoid bone.

It can be divided into three sites:

1. Pyriform sinus

2. Postcricoid area

3. Posterior pharyngeal wall
