The zygomatic process of the maxilla (malar process) is a rough triangular eminence, situated at the angle of separation of the anterior, zygomatic, and orbital surfaces.

• In front it forms part of the anterior surface.
• Behind it is concave, and forms part of the infratemporal fossa.
• Above it is rough and serrated for articulation with the zygomatic bone.
• Below it presents the prominent arched border which marks the division between the anterior and infratemporal surfaces.
