7up is the brandname of a lemon-lime flavored soft drink produced by the Dr Pepper/7Up company in the United States (a unit of Cadbury-Schweppes), and by Pepsi outside of the United States. 7up, originally named "Bib-Label Lithiated Lemon-Lime Soda", was concocted in 1929 in Saint Louis, Missouri. It originally contained lithium citrate. In the 1970s, an advertising campaign dubbed 7up the uncola.
There was an unrelated documentary film made in 1963 titled 7 Up.
