The sagittal suture is the serrated interlocking joint connecting the two paired parietal bones in the midline of the skull. It is one of the prominent sutures of the skull, easily identifiable from both superior and posterior views. It is a fibrous (suture) joint, that has no movement (synarthrosis).

It extends from its convergence with the coronal suture anteriorly, to its convergence with the lambdoid suture posteriorly. The point where the sagittal and coronal sutures meet is known as the bregma, which marks the location of the anterior fontanelle in the developing (neonatal) skull. The point where sagittal and lambdoid sutures meet is known as the lambda, with this point being at the apex of the occipital bone and typically in the middle of the lambdoid suture. The point also marks the location of the posterior fontanelle in the developing skull. The sagittal suture is the last suture in the skull to fuse, at around 30 years of age.
