Undisputed Attitude is the seventh studio album by American thrash metal band Slayer, released on May 28, 1996, by American Recordings. The album consists almost entirely of covers of punk rock and hardcore punk songs, and also includes two tracks written by guitarist Jeff Hanneman in 1984 and 1985 for a side project called Pap Smear; its closing track, "Gemini", is the only original track. The cover songs on the album were originally recorded by the bands the Stooges, Minor Threat, T.S.O.L., D.R.I., D.I., Dr. Know, and Verbal Abuse, whose work was prominently featured with the inclusion of cover versions of three of their songs. The album was initially to feature material from classic heavy metal artists such as Judas Priest, UFO and Deep Purple. "Gemini" was written by King and Araya several months before entering the recording studio. King asserts it is the only Slayer song on the album.

The band's cover of Minor Threat's "Guilty of Being White" raised questions about a possible message of white supremacy. The controversy involved the changing of the refrain "guilty of being white" to "guilty of being right", at the song's ending. This incensed Minor Threat frontman Ian MacKaye, who stated "that is so offensive to me". King said the lyric was altered for "tongue-in-cheek" humor, saying that the band thought racism was "ridiculous" at the time.

| rev6score = Paul Kott of AllMusic commented that "Undisputed Attitude, while not perfect, is a fitting tribute to the bands that inspired Slayer to break from the traditional metal mould." Entertainment Weekly Chuck Eddy dubbed Slayer's cover interpretations "generic hardcore-punk", and observed that the group "seem to think that playing as fast and rigidly as possible makes for harder rock -- but it's just lazy shtick."

Reviewing 2003 Slayer box set Soundtrack to the Apocalypse, Adrien Begrand of PopMatters dismissed the effort as "easily the weakest album in the Slayer catalogue", while Westword Online Michael Roberts dubbed the record their "biggest mistake." Araya has since stated that he "knew it wouldn't do very well, people want to hear Slayer! The real die-hards picked up on it and that was expected."
