"America's Sweetheart" is a song recorded by American singer and songwriter Elle King for her debut studio album, Love Stuff (2015). King co-wrote the song with its producer, Martin Johnson. It serves as the album's second mainstream single and the third overall (promoted concurrently with rock single "Under the Influence"), and was serviced to hot adult contemporary radio in the United States through RCA Records on February 8, 2016.
"America's Sweetheart" is a country pop and country rock song instrumented predominately by the banjo with a beat influenced by electronic dance music. The song's lyrics speak to the idea of nonconformity, with King outlining her unique qualities that conflict with the ideal persona of "America's sweetheart" and asserting that she refuses to change for anyone. King employs a belting technique on the chorus.
