Mandisa Diane Hundley, most commonly known simply as Mandisa (born October 1, 1976) is an American singer and was the ninth‑place finalist in the fifth season of American Idol.

Mandisa grew up in Citrus Heights, California (Sacramento County) and graduated from El Camino Fundamental High School. She then attended American River College in Sacramento where she studied Vocal Jazz. Then she was off to Fisk University in Tennessee and graduated with a bachelor's of music degree with a concentration in vocal performance. Mandisa currently resides in the suburban Nashville community of Antioch, Tennessee. When she auditioned for American Idol in Chicago, she asked the judges to call her «just Mandisa», and she has been billed as Mandisa (with no last name) on the show since the show's Hollywood round. Mandisa was a backup singer for famed Christian author and speaker Beth Moore. She has stated her musical influences run the gamut from Whitney Houston to Def Leppard.

Idol judge Simon Cowell made several comments about Mandisa's weight during her audition. When he first saw her, he quipped are we «going to have a bigger stage this year.» Later, when Paula Abdul commented that Mandisa had a «Frenchie» growl to her voice, Cowell responded that a more apt comparison would be to France itself. These were among comments that drew the ire of the National Association to Advance Fat Acceptance, and would be one of the reasons Mandisa would entitle her 2007 album «True Beauty».
