"Nobody Knows Me" is a song by American singer-songwriter Madonna. The song was written and produced by Madonna and Mirwais Ahmadzaï for her ninth studio album American Life (2003). It was released as a promotional single in the United States on October 15, 2003, with a remixed version appearing on the remix compilation Remixed & Revisited (2003). "Nobody Knows Me" carries on the main theme of American Life, with its usage of negative tones on the songs. It is a dance and electronic song, with vocoder effects, spacey synths and a bubbly bass, and lyrically, Madonna rejects tabloid culture's "social disease", denouncing both TV and magazines.

American Life is the ninth studio album by American singer Madonna. It was released on April 21, 2003, by Maverick and Warner Bros. Records. The album, produced by the singer and Mirwais Ahmadzaï, features references to many parts of American culture. The album is a concept album, with themes panning the American Dream and materialism. These themes reject the reputation Madonna held in the 1980s, earned by songs such as her 1984 Billboard Hot 100 number-two hit, "Material Girl". American Life is a folktronica and eurotechno album, influenced by acoustic music.
