在人类解剖学中，翼腭窝（pterygopalatine fossa，或sphenopalatine fossa）为人类颅骨中一个窝状构造。翼腭窝共有一对，为颞下窝内侧的一个圆锥状凹窝。该窝位于上颌骨后方。翼颚窝位于翼上颌裂内侧，通往蝶颚孔，可通向鼻腔、口腔、颞下窝、眼眶，及咽，另有8个孔通向中颅窝。

翼腭窝向外通颞下窝，向前藉眶下裂通眶面，向内藉腭骨于蝶骨围成的蝶腭孔通鼻腔，向后藉圆孔通颅中窝，藉翼管通颅底外面，向下移行至腭大管，继而经腭大孔通口腔。

In human anatomy, the pterygopalatine fossa (sphenopalatine fossa) is a fossa in the skull. A human skull contains two pterygopalatine fossae -- one on the left side, and another on the right side. Each fossa is a cone-shaped paired depression deep to the infratemporal fossa and posterior to the maxilla on each side of the skull, located between the pterygoid process and the maxillary tuberosity, close to the apex of the orbit. It is the indented area medial to the pterygomaxillary fissure leading into the sphenopalatine foramen. It communicates with the nasal and oral cavities, infratemporal fossa, orbit, pharynx, and middle cranial fossa through eight foramina.
