"Fallen" is a song by American recording artist Mýa, released as the second and final single from her third studio album, Moodring (2003). The song was written by Rich Shelton, Kevin Veney, Loren Hill, and Leonard Huggins. It contained excerpts from Luiz Bonfá's 1963 song "Saudade Vem Correndo", written by Bonfá and Maria Toledo. The lyrics of the mid-tempo track speak of a woman falling head over heels in love with someone.
The song received generally positive reviews from contemporary music critics, complimenting Mýa's voice and its arrangements. "Fallen" underperformed on the Billboard Hot 100, where it peaked at number fifty-one and spent two non-consecutive weeks. It fared better on Billboards Hot R&B/Hip-Hop Songs chart, reaching number thirty-five. Due to its lackluster chart performance stateside, the single was not released internationally. "Fallen" remains Mýa's last single to chart on the Hot 100, as well as her final single released under Interscope Records.
The song's accompanying music video, directed by Darren Grant and filmed in Toronto, featured Mýa stalking a potential lover. The video made its world premiere on BET's Access Granted in October 2003. "Fallen" and its Zone 4 remix featuring rapper Chingy were included on the soundtrack to the 2004 films A Cinderella Story and Barbershop 2: Back in Business, respectively.
