The coracoacromial ligament is a shoulder girdle ligament made of connective tissue that connects different structures of the scapula. It also forms the upper vault of the glenohumeral (shoulder) joint.

The ligament has a triangular shape. Its apex is attached to the summit of the acromion near the clavicular articulating surface, while its base inserts along the lateral part of the coracoid process of the scapula.
