Emmental, Emmentaler, or Emmenthal is a yellow, medium-hard cheese that originated in the area around Emmental, in the canton of Bern in Switzerland. It is classified as a Swiss-type or Alpine cheese.

Emmental was first mentioned in written records in 1293, but first called by its present name in 1542. It has a savory but mild taste. While "Emmentaler" is registered as a geographical indication in Switzerland, a limited number of countries recognize the term as a geographical indication: similar cheeses of other origins, especially from France (as Emmental), the Netherlands, Bavaria, and Finland, are widely available and sold by that name. In some parts of the world, the names "Emmentaler" and "Swiss cheese" are used interchangeably for Emmental-style cheese.
