The suboccipital triangle is a region of the neck bounded by the following three muscles:

* Rectus capitis posterior major - above and medially
* Obliquus capitis superior - above and laterally
* Obliquus capitis inferior - below and laterally

It is covered by a layer of dense fibro-fatty tissue, situated beneath the Semispinalis capitis.

The floor is formed by the posterior occipito-atlantal membrane, and the posterior arch of the atlas.

In the deep groove on the upper surface of the posterior arch of the atlas are the vertebral artery and the first cervical or suboccipital nerve.
