The suprapineal recess is an anatomical structure in the ventricular system of the brain. It is located in the posterior part of the third ventricle, overlying the cerebral aqueduct.^[1]

In severe cases of hydrocephalus with increased pressure, this structure can dilate causing mass effect on the midbrain resulting in Parinaud's syndrome with bilateral inward and downward deviation of the eyes.
