The awards and decorations of the United States Armed Forces include various medals, service ribbons, ribbon devices, and specific badges which recognize military service and personal accomplishments of members of the U.S. Armed Forces. Such awards are a means to outwardly display the highlights of a service member's career.

A medal ribbon, service ribbon or ribbon bar is a small ribbon, mounted on a small metal bar equipped with an attaching device, which is generally issued for wear in place of a medal when it is not appropriate to wear the actual medal. Each country's government has its own rules on what ribbons can be worn in what circumstances and in which order. This is usually defined in an official document and is called "the order of precedence" or "the order of wearing." In some countries, some awards are "ribbon only," having no associated medal.
