"Underneath the Tree" is a song by American recording artist Kelly Clarkson, from her sixth studio album and first Christmas album, Wrapped in Red (2013). Written by Clarkson along with Greg Kurstin, who handled its production, it is a Christmas-themed song that sings of gratitude for companionship during the holidays, in which the beloved is being referred as the only present needed "underneath the tree". Accompanied by various instrumental sounds, the song prominently incorporates a Wall of Sound treatment along with sleigh bells and bell chimes to resonate a holiday atmosphere. "Underneath the Tree" was first released to Adult Contemporary radio stations on November 5, 2013, by RCA Records as the lead single from the album.

"Underneath the Tree" has been praised by music critics, who considered it as the main highlight of Wrapped in Red and lauded its potential to be a holiday classic. They also complimentarily compared it to the 1994 modern Christmas standard "All I Want for Christmas Is You" by Mariah Carey. The song reached number one on U.S. and Canada adult contemporary charts and reached the top 40 in Canada, the Netherlands, South Korea, and the United Kingdom.

Filmed by English director Hamish Hamilton, the accompanying music video for the song features a live performance from the television special Kelly Clarkson's Cautionary Christmas Music Tale at The Venetian Las Vegas. Apart from the television special, Clarkson has also performed it in various televised performances, such as Late Night with Jimmy Fallon and the American singing competition The Voice.
