In anatomy, the scapula (plural scapulae or scapulas; also known as shoulder bone, shoulder blade or wing bone) is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones the scapulae are paired, with the scapula on either side of the body being roughly a mirror image of the other. In early Roman times, people thought the bone resembled a trowel, a small shovel.

The name scapula as synonym of shoulder blade is of Latin origin. It is commonly used in medical English and is part of the current official Latin nomenclature, Terminologia Anatomica. In classical Latin scapula is only used in its plural scapulae. Although some sources mention that scapulae is used to refer during Roman antiquity to the shoulders or to the shoulder blades, others persist in that the Romans used scapulae only to refer to the back, in contrast to the pectus, the Latin name for breast or chest.
