A garnish is an item or substance used as a decoration or embellishment accompanying a prepared food dish or drink. In many cases, it may give added or contrasting flavor. Some garnishes are selected mainly to augment the visual impact of the plate, while others are selected specifically for the flavor they may impart.

Many garnishes are not intended to be eaten, though for some it is fine to do so. Parsley is an example of a traditional garnish; this pungent green herb has small distinctly shaped leaves, firm stems, and is easy to trim into a garnish.

A garnish makes food or drink items more visually appealing. They may, for example, enhance their color, such as when paprika is sprinkled on a salmon salad. They may provide a color contrast, for example when chives are sprinkled on potatoes. They may make a cocktail more visually appealing, such as when a cocktail umbrella is added to an exotic drink, or when a Mai Tai is topped with any number of tropical fruit pieces.
