"Just Lose It" is a song by American rapper Eminem from his fifth studio album Encore (2004). It was released as the lead single from Encore, and was later included on his greatest hits compilation album Curtain Call: The Hits (2005). The song caused controversy as its lyrics and music video parodies Michael Jackson, who was being accused of child molestation at the time. The song also pokes fun at Beavis/Cornholio, MC Hammer, Madonna, and others. It also heavily spoofs Pee-wee Herman, going as far as imitating his signature shout during the chorus and Eminem dressing like him in the video.

The song reached number one in the United Kingdom, Australia and New Zealand, and number six in the United States Billboard Hot 100. Despite charting high, the song did not perform as well as his two previous lead singles, "The Real Slim Shady" (2000), and "Without Me" (2002).

Two skits regarding the Michael Jackson controversy were included on Encore, "Paul (Skit)" and "Em Calls Paul (Skit)". The lyrics to "Just Lose It" refer to Jackson's legal troubles, however he does state in his song "... and that's not a stab at Michael, That's just a metaphor, I'm just psycho...." At the beginning of the song there is a lyrical excerpt from Eminem's 2002 single "Without Me" about how "Shady's back". The line "Snap back to reality. Look! It's B. Rabbit" and "You signed me up to battle" refers to "Lose Yourself" and Eminem's character in the movie 8 Mile. In the second verse of the song there is a line "So fellas, fellas..." which is a reference to Sir Mix-a-Lot's song "Baby Got Back". The line "Girl you know you're my world," from the chorus, is a reference to the chorus of his song "Superman" from his album The Eminem Show.
