Beauty and the Geek is an American reality television series that premiered on The WB on June 1, 2005. It has been advertised as "The Ultimate Social Experiment" and is produced by Ashton Kutcher, Jason Goldberg and J. D. Roth. The show's title is a parody of Beauty and the Beast. This was the first show produced by the Fox Television Studios sub-division Fox 21.

The show follows groups of "Beauties" (people — almost always women — who rely on their attractiveness and outgoing personalities but typically lack intellect) and "Geeks" (people — almost always men — who rely on their intellect, but typically lack social ability) who must pair up to compete in challenges to avoid elimination. The final pair remaining is declared as being "More than just a Beauty and a Geek" and wins the grand prize of $250,000.

While a competition, the show is also billed as a social experiment, in which each contestant typically learns from his or her teammate. During the competition, the contestants live in a mansion and compete in a series of challenges, with the beauties competing in challenges of intellect, and the geeks competing in challenges involving social ability.
