A Badge is a device, patch, or accoutrement which is presented or displayed to annote some feat of service, a special accomplishment, or as a simple means of identification.

In the military, badges are often used to denote qualifications received through military training. Similarly, scouting organizations use them to show group membership and rank.

One of the best-known badges is the typically star-shaped U.S. sheriff's badge, made famous in Westerns.

The BBC children's program Blue Peter also awards its own "Blue Peter badge" to members of the public who appear on the show.
