The floor of the [[orbit]] is formed by the orbital plate of the [[maxilla]], the orbital surface of [[zygomatic bone]], and the orbital process of the [[palatine bone]].

The [[orbital floor]] is continuous with the medial wall, except in the most anterior part, where the floor is perforated by the [[nasolacrimal canal]] (NLC). The anterior part of the floor is continuous with the lateral wall, but posteriorly, the floor and lateral wall are separated by the [[inferior orbital fissure]](IOF). The [[infraorbital groove]] (IOG) leads forward out of the inferior orbital fissure to cross the floor to reach the [[infraorbital canal]], which ends below the lower orbital rim in the [[infraorbital foramen]].
