"U.G.L.Y." is a song by American recording duo Daphne & Celeste. It was released on June 5, 2000, as the second single from their studio album, We Didn't Say That!. The song was written and composed by Michele Chiavarini, Tracy Kilrow, Michael Marz and S. Burkes, while its producer was Chiavarini. "U.G.L.Y." is a teen pop and bubblegum pop song with a cheerleading style, making it similar in this respect to Toni Basil's song "Mickey". Lyrically, the song is about people who Daphne & Celeste think are ugly.

The song received mixed reviews from music critics, with some saying it was a good single, but many panning it and at least one reportedly saying it was "inappropriate and ridiculous". It is still the subject of criticism to this day due to its harsh lyrics. Although it received unfavorable reviews upon its release as a single, the song did very well in New Zealand, where it peaked at number seven (its highest position on any chart anywhere in the world). Elsewhere it wasn't quite so successful, but the single would later be immortalized in the American box office hit film Bring It On (released August 2000) and its accompanied soundtrack.
