"U.N.I.T.Y." is a song by American hip-hop artist Queen Latifah from her third studio album, Black Reign (1993). The single was released on November 9, 1993, in the United States, and on January 6, 1994, in the United Kingdom. "U.N.I.T.Y." focused on confronting disrespect of women in society, addressing issues of street harassment, domestic violence, and slurs against women in hip-hop culture.

Because of its message, many radio and television stations would play the song without censoring the words "bitch" and "hoes", which appear often in the lyrics, particularly the chorus and the line, "who you callin' a bitch?!" that ends each verse of the song. The song samples "Message from the Inner City" by the Crusaders, a Houston based jazz group. The song was also featured on Living Single, Latifah's series which began the same year.

There is a second version of song, which gained airplay, titled "U.N.I.T.Y. (Queen Ruff Neck Boot)". The second version has a similar beat to the album version, replacing much of the jazz sample with a hip-hop beat. The second version can be found as a clean version on 20th Century Masters: The Millennium Collection: The Best of Queen Latifah and Hip Hop: Gold.

"U.N.I.T.Y." won the 1995 Grammy Award for Best Rap Solo Performance. The song remains Latifah's biggest hit single in the United States to date, and her only song to reach the Top 30 of the Billboard Hot 100.
