This article is about a bone. For a book, see Malleus Maleficarum.

The malleus is hammer-shaped small bone or ossicle of the middle ear which connects with the incus and is attached to the inner surface of the eardrum.

It transmits the sound vibrations from the eardrum to the incus.

The malleus is unique to mammals, and evolved from a lower jaw bone in reptiles called the articular.
