Diet Mountain Dew (also known in Denmark and Finland as "Free MD," in the United Kingdom, Netherlands, Sweden, Norway, and Spain as "MD All Dew - No Sugar, and in New Zealand as "MD No Sugar") is a Mountain Dew variant with only 10 calories, compared to the 290 calories in the original. Its tagline is "Zero calorie DEW."


Diet Mountain Dew is a modified version of the original formula, containing very less sugar, but retaining the same citrus taste and yellow-green color as the original Mountain Dew drink, similar to, Mountain Dew Zero Sugar.


Diet Mountain Dew was first introduced alongside Caffeine-Free Mountain Dew in 1976 in response to the growing trend in America of weight-watching. It used to be branded as Sugar-Free Mountain Dew until 1984 when it was renamed to Diet Mountain Dew, its current name.

In 2006, Diet Mountain Dew was reformulated with a new "Tuned Up Taste", using a blend of sucralose, aspartame, and acesulfame potassium as sweeteners. The previous formulation was sweetened exclusively with aspartame.

Starting in 2020, a new zero-sugar variant called Mountain Dew Zero Sugar will hit the shelves in the United States. A PepsiCo employee stated the Diet Mountain Dew variant will not be replaced. Instead, it will coexist with Zero Sugar. In Canada, however, Diet Mountain Dew was officially replaced with Mountain Dew Zero Sugar since March 2020.
