The sagittal suture is a dense, fibrous connective tissue joint between the two parietal bones of the skull. At birth, the bones of the skull do not meet. If certain bones of the skull grow too fast then "premature closure" of the sutures may occur. This can result in skull deformities. If the sagittal suture closes early the skull becomes long, narrow, and wedge-shaped, a condition called "scaphocephaly."

Two anatomical landmarks are found on the sagittal suture: the bregma and the vertex of the skull. The bregma is formed by the intersection of the sagittal and coronal sutures, and the vertex is the highest point on the skull and is many times near the midpoint of the sagittal suture.

The sagittal suture is also known as the "interparietal suture" and the "sutura interparietalis."
