"Who Is It" is a song by American recording artist Michael Jackson. It was released by Epic Records on August 31, 1992, as the fifth single from Jackson's eighth studio album, Dangerous (1991). The song was written and composed by Jackson, and produced by Jackson and Bill Bottrell. The song's lyrics pertain to despair over being left by someone you love; some critics noted a comparison to the lyrics of the song to Jackson's single, "Billie Jean", from the album Thriller. As part of the promotion for the song, two music videos were released in 1992. The song was not performed by Jackson on any of his world concert tours. He did, however, perform a small segment of the song in his interview with Oprah Winfrey in early 1993. The instrumental version of the song was supposed to be used during the "This Is It concerts," which were canceled due to Jackson's death.
"Who Is It" was recorded by Michael Jackson in 1990 for his eighth studio album, Dangerous, which was released the following year. Jackson wrote and composed the track, and produced it with Bill Bottrell. It was released as the fifth single from Dangerous on August 31, 1992, by Jackson's record label, Epic Records. The lyrics of the song tell of a man who is left in despair when his lover suddenly leaves him. He learns that she was unfaithful to him and wants to know with whom the person was that she cheated.
Several music critics compared "Who Is It" to Jackson's 1983 single "Billie Jean". Jon Pareles, a writer for The New York Times, described "Who Is It" as an "imitation" of "Billie Jean". Chris Willman of the Los Angeles Times claimed that the track "recaptures some of the slinky, insinuating feel of 'Billie Jean.'" Jonathan Bernstein, a writer for Spin, wrote that "Who Is It" was "close skin to "Billie Jean". Alan Light of Rolling Stone noted that unlike his previous efforts, it is about betrayal.
"Who Is It" was commercially successful worldwide, generally peaking within the top thirty positions on national music charts. The song peaked at number fourteen on the United States' Billboard Hot 100 chart, while peaking at number six on BillboardHot R&B/Hip-Hop Songs, as well as topping the BillboardHot Dance Club Play.

It begins with Jackson in what seems to be a hotel, singing about his girlfriend. He is distressed because he found a silver card in with the name "Alex" on it. To him, it implies that "Alex" is another man who his girlfriend is with; thus, she is cheating on Jackson. However, as the story in the video unfolds, this is not true, because the girl takes on different identities (I.e. Eve, Diana, etc.) for her job as a high class call girl. "Alex" (which is also a girl's name), just happens to be one of them. The video alternates scenes from where Jackson is singing about his pain, to where the girl is being changed into her different identities and taking care of her jobs (mostly meeting with other men and even some women and sleeping with them). Towards the end of the video, Jackson has packed up his bags to leave town, because of his distress. A helicopter comes to pick him up from his house. The girl comes to Jackson's house and she asks his assistant (who knows the situation and aided Jackson in his departure) to let her in. The assistant shakes his head, implying that he left. When she asks why, he drops a flutter of silver nameplates (including the one that said "Alex") from a slot in the door. After that scene, Jackson is seen sleeping and smoke floats out the side of the screen. The girl regrets and takes off her makeup to quit what she was doing.
