"Bang" is a song by Brazilian pop singer Anitta, from her third studio album of the same name (2015). It was written by the singer along with Umberto Tavares and Jefferson Junior. The producer Mãozinha was credited as co-producer. The song was released on 9 October 2015, serving as the second single from the album. The song is the most watched female video on YouTube Brazil and the 7th most watched music in general in 2015, with nearly 60 million views.

Upon release the song received mixed reviews from music critics, who praised its sound, but criticized the lyrics for being "weak". It managed to reach top ten on Billboard Hot 100 Airplay Brazil, and also managed to stand out in Brazil's regional charts, such as Fortaleza, Recife, Rio de Janeiro, São Paulo and Vitória. According to Anitta, "Bang" brings a "step by step" of how one should do to be in the same tune as another, also commenting that this can be sung for any type of audience, being, for this, a "singing of victory". A song about some kind of partnership, it's derived from the pop and trap genres, with electronic and funk influences from the 1970s.

The corresponding music video was directed by Bruno Ilogti, directed by Giovanni Bianco, with more than 50 professionals involved in the production. The intention was that the video would show a message of "strength, self-esteem, and at the same time a new step in [Anitta's] career."

A campaign was announced on Twitter, in which fans could earn the chance to attend the premiere party of the video. To achieve that, they should use a hashtag with the name of the song and the state the lived in. A controversy occurred during the promotion, when Cid, owner of famous Brazilian comedy website Não Salvo, told his followers to mention the state of Acre.

The song is featured on the music game Just Dance 2017.

According to Anita, the song was inspired by images created by Giovanni Bianco for her third studio album. The singer wanted the album to be "a clear shot:" "I told Giovanni that I wanted something revolutionary, that people would enjoy, something universal. He took this idea of 'power', of bang, of 'the right shot'. This happened seven months ago and the song didn't exist back then. Then I thought: 'I have to have song with this bang on it,'" leading the singer to write the song.
