"Mic Drop" is a song recorded by South Korean boy group BTS for their fifth extended play Love Yourself: Her (2017). The song was first released by Big Hit as a B-track on September 18, 2017, in South Korea. The song was remixed by American DJ Steve Aoki featuring rapper Desiigner and was released to American contemporary hit radio as a single. The remix by Aoki was released with a music video.

On December 6, 2017, the Japanese music video for "MIC Drop" was released.

At a press conference, BTS member RM revealed that the song was inspired by former US president Barack Obama's mic drop at his last White House Correspondents' Dinner in 2016.

BTS garnered attention in the US during 2017 after appearences and performances on music award shows and on the Billboard charts. On September 17, 2017, it was announced that the group will release a single album on December 6 that includes the Japanese version of "DNA" and "MIC Drop" along with a new song titled "Crystal Snow".

The album track "Mic Drop" is a hip hop number. A Billboard writer described it as "an energetic hype song about BTS' global popularity." The Steve Aoki-produced version introduces EDM synths and trap beats over the original melody, and English-speaking verses from the band. An alternate version of "Mic Drop" features an opening verse from Desiigner featuring the rapper's "fast-talking."

The music video director Woogie Kim stated in an interview: "Listening to the song, the first thing that came to my mind was that I wanted to lock BTS in an interrogation room. Then I wanted to show the viewers how they managed to escape and free themselves with music." On November 16, 2017, they released a teaser for the song. After the original release date of November 17 was pushed back due to their American schedule, the video was released on November 24.
