The jugal is a skull bone found in most reptiles, amphibians, and birds. In mammals, the jugal is often called the malar or Zygomatic. It is connected to the quadratojugal and maxilla, as well as other bones, which may vary by species.

This bone is considered key in the determination of general traits of the skull, in the case of creatures, as with dinosaurs in paleontology, whose entire skull has not been found.
