Slim Shady EP is the only extended play by American rapper Eminem, released on December 10, 1997, through Web Entertainment.

Unlike his debut album Infinite (1996), Slim Shady EP helped Eminem gain the interest of CEO Jimmy Iovine (co-founder of Interscope Records) and West Coast hip-hop rapper and producer Dr. Dre, who subsequently signed Eminem to his Aftermath Entertainment record label, and served as executive producer on his major-label debut album The Slim Shady LP (1999).

His lyrics are a marked departure from those found on Infinite, featuring constant references to drug use, sexual acts, mental instability, and over-the-top violence.

Another departure was his exploration of more serious themes of dealing with poverty, his direct and self-deprecating response to criticism, and of marital and family difficulties.

The production value of the music on the tracks—from previous collaborators DJ Head, the Bass Brothers, and Mr. Porter—was also noticeably higher than on prior album efforts.

"[2] After the release of Infinite, Eminem's personal struggles and abuse of drugs and alcohol culminated in a suicide attempt: all these troubles became main themes of Slim Shady EP.

[3] The disappointment of Infinite inspired Eminem to create the alter ego Slim Shady: "Boom, the name hit me, and right away I thought of all these words to rhyme with it".

[2] He placed second, and the staff at Interscope Records who attended the Rap Olympics sent a copy of the Slim Shady EP to company CEO Jimmy Iovine.
