7 Up (stylized as 7up outside the U.S.) is a brand of lemon-lime-flavored non-caffeinated soft drink. The rights to the brand are held by Keurig Dr Pepper in the United States and by 7 Up international in the rest of the world. The U.S. version of the 7 Up logo includes a red circle between the “7” and “Up”; this red circle has been animated and used as a mascot for the brand Cool Spot. Before that, the mascot was a fictional character named Fido Dido created by Joanna Ferrone and Sue Rose. He is still used outside the U.S. for the limited time only 7 Up retro cups.

A myth exists that the 7 Up name comes from the drink having a pH over 7. That would make it neutral or basic on the scale; however, this is not the case, as the 7 Up pH is close to 3.79, making it acidic on the pH scale and similar to other drinks of this type. The real origin of the name is unclear, though Britvic claims that the name comes from the seven main ingredients in the drink, while others have claimed that the number was a coded reference to the lithium contained in the original recipe, which has an atomic mass around 7. Britvic also claims that the name is a result of the fact that 7 Up was bottled in 7-ounce bottles (Coca-Cola and most other soft drinks were bottled in 6-ounce bottles) .
