"Reality" is a song by French composer Vladimir Cosma, performed by English singer Richard Sanderson. It was released in 1980 as part of the soundtrack to the popular 1980 French film La Boum, which starred French actress Sophie Marceau (who later starred in popular films such as Academy Award-winning Braveheart and James Bond franchise The World Is Not Enough). It also served as the theme song to the 2011 Korean film Sunny.

"Reality" is a ballad composed and written by Vladimir Cosma (under the name of Jeff Jordan) and produced by Pierre Richard Muller. Between 1980 and 1982, then in 1987 after its re-release, it became a major hit in Europe and Asia, topping the charts in fifteen countries including Germany, France, Italy, Austria, Finland and Switzerland. The song led Richard Sanderson to stardom, giving him more hits with Cosma such as "Your Eyes", "She's a Lady", and "Sun".

"Reality" has been covered many times by various artists, including one singing a Spanish version of the song ("Mi realidad"). On DSDS, the German equivalent of American Idol, the song has been sung multiple times. In the film La Boum, it also appears frequently (usually during the actors' romantic scenes), being the film's main theme song. For the film's 1982 sequel, La Boum 2, the main song was changed to "Your Eyes", performed by Cook da Books. Because "Reality" has the same key as "Go On Forever" (another song played in the last part of the film, from the La Boum soundtrack and sung by Sanderson and Chantal Curtis), both songs are musically linked at the end of the film.

The La Boum soundtrack album, which features the song "Reality", was made available on iTunes in 2009 by Larghetto.
