The smallest bone in the human body is the stapes , and it is located deep inside the ear, in the middle ear just behind the eardrum.

Quick Scoop

  • The stapes is part of a tiny chain of three ear bones called the ossicles (malleus, incus, stapes).
  • It sits between the incus and the oval window of the inner ear, helping transmit sound vibrations to the cochlea so you can hear.
  • Despite being only a few millimeters in size, this bone plays a crucial role in normal hearing, and damage to it can lead to hearing loss.
