Beat Down is a song by music producers Steve Aoki and Angger Dimas, featuring vocals from Australian rapper Iggy Azalea. The song was included on the re-release of Aoki's debut studio album, entitled Wonderland (Remixed), which was released on July 10, 2012.

Aoki released his long-awaited debut studio album, Wonderland, on January 10, 2012, featuring guest vocalists and musicians LMFAO, Kid Cudi, Kay, Travis Barker, will.i.am aka Zuper Blahq, Wynter Gordon, Rivers Cuomo, Lil Jon, Chiddy Bang, Lovefoxxx of CSS, Big John Duncan (former guitarist of the punk band The Exploited), and others, through his record label Dim Mak. A remix album was released shortly after, on July 10, 2012, Wonderland (Remixed), featuring a new original track that would become the lead single of the project, "Beat Down," with fellow Indonesian electronic producer/DJ Angger Dimas and also featured up-and-coming Australian rapper Iggy Azalea, who had been featured on the cover of hip-hop magazine XXL's buzzed-about annual "Top 10 Freshman List" and announced signing a deal with Southern rapper T.I.'s Grand Hustle Records.

Becky Bain of Idolator claimed the track is "a solid tune that is ready to pump you up" and complimented Azalea's guest appearance adding that "the Aussie rapper lays down some serious flow." DJ Booth also praised it saying, "If you're a fan of EDM and a lover of 808s and snares, then you'll probably wear out the repeat button after listening to this single. Iggy does surprisingly well with the complex track as she professes that she's well versed in the art of the beat down with lyrics like, "It's a party on your face and I'm about to dance on it"," while Noisey drew comparisons to Major Lazer's 2009 single "Pon de Floor".
