Sara Beth Bareilles (born December 7, 1979) is an American singer-songwriter and pianist. She achieved mainstream success in 2007 with the hit single "Love Song", which brought her into the number one spot on the Billboard Pop 100 chart.

After graduating from college in 2002, Bareilles performed at local bars and clubs (such as the Hotel Cafe and Genghis Cohen in Los Angeles), building a following, before performing in larger venues. She issued two demos of mostly live tracks in 2003: The First One in April and The Summer Sessions in October. In 2004, she appeared as a singer in a bar in the indie film Girl Play, performing the song "Undertow".

In January 2004, Bareilles released her first studio album, Careful Confessions. She signed a contract with Epic Records' A&R executive Pete Giberga on April 15, 2005. The remainder of the year and early 2006 were spent writing and reworking songs for her upcoming album. Her song, "Gravity," appears briefly in the 2006 independent film Loving Annabelle. She also toured as the opening act in 2006 for Marc Broussard's "Carencro" tour.

In mid-2004 she opened for Rocco DeLuca and the Burden during their inaugural headline tour, supported Guster on their first UK tour and co-headlined a tour with Jon McLaughlin. In 2007, Bareilles toured as the opening act for Aqualung and Mika, and later that year opened for several shows on both Maroon 5 and Paolo Nutini's U.S. tours. She also opened for James Blunt on his U.S. Tour in association with VH1 You Oughta Know.
