The Occipitofrontalis is a muscle of the human body, with two parts:

• the "occipital" part/belly, near the occipital bone.
• the "frontal" part/belly, near the frontal bone.

Some sources consider the Occipitofrontalis to be a structure consisting of two distinct muscles, the Frontalis and the Occipitalis. However, Terminologia Anatomica currently classifies it as a single muscle.
