Of the three borders of the scapula, the superior border (or superior margin) is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process.

At its lateral part is a deep, semicircular notch, the scapular notch, formed partly by the base of the coracoid process.

This notch is converted into a foramen by the superior transverse ligament, and serves for the passage of the suprascapular nerve; sometimes the ligament is ossified.

The adjacent part of the superior border affords attachment to the Omohyoideus.
