In anatomy, the term nasal meatus^[1] can refer to any of the three meatuses (passages) through the skull's nasal cavity: the superior meatus (meatus nasi superior), middle meatus (meatus nasi medius), and inferior meatus (meatus nasi inferior).

The nasal meatuses are the spaces beneath each of the corresponding nasal conchae. In the case where a fourth, supreme nasal concha is present, there is a fourth supreme nasal meatus.
