Sweet Lightning is a Mountain Dew flavor exclusively available in soda fountain machines only at KFC restaurants released at the start of April 2019 in the United States.


Sweet Lightning is a Sweet Peach and Smooth Honey flavor of Mountain Dew and is yellow-orange in color. It is similar to the cancelled flavor Happy Dew Year, which partly has a similar shade of peach flavor. It is also close to the relationship between Taco Bell and Baja Blast of having a proprietary beverage chemically, specifically designed to taste best for the food that the restaurant serves.


Its tagline is "DEW charged with Natural & Artificial Sweet Peach & Smooth Honey".


On March 4th, 2019, PepsiCo filed a trademark for Sweet Lightning titled "MTN DEW SWEET LIGHTNING." It was then quickly rumored that Sweet Lightning would get released exclusively at KFC restaurants, which was later proven in a Reddit post weeks later.

On March 31st, 2019, in a r/MountainDew Reddit post, Sweet Lightning got first leaked by a user named "FightingCommander," showing an image of Sweet Lightning in a soda fountain. This was the first confirmed sighting of Sweet Lightning, with further sightings appearing after.

As of September 2021, Sweet Lightning is still available within all KFC restaurant locations nationwide since July 1st, 2019.
