The superior rectus muscle is a muscle in the orbit. It is one of the extraocular muscles.

It is innervated by the superior division of the oculomotor nerve (Cranial Nerve III).

In the primary position (looking straight ahead), the superior rectus muscle's primary function is elevation, although it also contributes to intorsion and adduction.
