"Purple Pills", also known as the censored version, "Purple Hills", is a hip hop single by American rap group D12, taken as the second cut from their debut studio album, Devil's Night. It achieved notable success, peaking at number nineteen on the Billboard Hot 100, number two in the United Kingdom, the Republic of Ireland and Norway, number three in Australia, number five in Sweden and number ten in the Netherlands and Finland.

The track features verses rapped by Eminem, Bizarre, Proof, Swifty and a joint verse between Kuniva and Kon Artis. The album version of the song contains many references to drug use, with "purple pills", "golden seals", and "Mushroom Mountain" being examples of recreational drug use. When it was announced that the group intended to release the track as a single, due to the drug and sex references, it was deemed inappropriate for play on many radio stations, and as such, a censored version of the song, "Purple Hills", was made. This version removes most of the drug and sex references, and replaces them with comical lyrics. Such changes include; the line "I've been to mushroom mountain" altered to say "I've climbed the highest mountain"; and the line "I take a couple uppers, I down a couple downers" changed to "I've been so many places, I've seen so many faces." Most of Bizarre's verse is entirely changed, due to the strong amount of sexual and drug content in it. Music videos were made for both "Purple Pills" and "Purple Hills". The accompanying music videos were directed by Joseph Kahn.

In the United States and United Kingdom, radio play was limited to "Purple Hills", as "Purple Pills" was deemed not suitable for radio. However, a number of underground radio stations in the United States played "Purple Pills". Music channels were also restricted to playing the video for "Purple Hills". When physically released, two versions of the single were made available in the United Kingdom — one for "Purple Pills", with the "Purple Pills" audio track and music video, and one for "Purple Hills", with the "Purple Hills" audio track and music video. In Europe and Australia, one version of the single was available—this contained "Purple Pills" as an audio track but the music video for "Purple Hills". In America, one version of the single was available — this contained "Purple Hills" as an audio track with no enhanced section.
