In human anatomy, the sternocleidomastoid muscles are muscles in the neck that act to flex and rotate the head.

It is given the name sternocleidomastoid because it attaches to the sternum (sterno-), the clavicle (cleido-), and the mastoid process of the temporal bone of the skull.

Its motor innervation is the 11th cranial nerve (the spinal accessory or accessory nerve). Its sensory innervation is the cervical plexus.

Its blood supply comes from the occipital artery and the superior thyroid artery.
