A medal ribbon is a strip of fabric, often worn around the neck or attached to a uniform, that holds a military or civilian decoration or medal. It's an important component of a military or ceremonial uniform and serves to display the medal and its associated honor.

Medal ribbons come in various colors and designs, each representing a specific campaign, service, or award. The colors, patterns, and arrangements of these ribbons can vary widely between different countries and even within different branches of a military.

For example, in the United States, each branch of the military has its own set of ribbons, and individual awards and decorations are denoted by different combinations of these ribbons. Similarly, many other countries have their own systems for displaying medals and honors through ribbons.

In addition to military medals, ribbons can also be used for various civilian awards, such as those given for community service, academic achievements, or other forms of recognition.
