The '''infraspinous''' '''fossa''' ('''infraspinatus fossa''' or '''infraspinatous fossa''') of the [[scapula]] is much larger than the [[supraspinatous fossa]]; toward its [[Medial border of scapula|vertebral margin]] a shallow concavity is seen at its upper part; its center presents a prominent convexity, while near the [[Lateral border of the scapula|axillary border]] is a deep groove which runs from the upper toward the lower part.

The medial two-thirds of the fossa give origin to the [[infraspinatus]]; the lateral third is covered by this muscle.
