The occipital vein (Latin: vena occipitalis) is a blood vessel that arises from the posterior venous plexus in the scalp.
The occipital vein penetrates the cranial attachment of the trapezius and dips into the suboccipital triangle, where it joins the deep cervical and vertebral veins.
The main tributaries of the occipital veins are the occipital emissary veins that connect the occipital vein with the intracranial confluence of sinuses via the mastoid and parietal foramina and the posterior condylar canal.
The occipital vein drains into either of the following veins:
- internal jugular vein,
- posterior auricular vein,
- deep cervical vein,
- vertebral vein.
The occipital vein collects blood from the occipital region of the head.
