"Gorilla" is a song by American recording artist Bruno Mars from his 2012 studio album Unorthodox Jukebox. The song was written by Mars, Philip Lawrence and Ari Levine, while production was handled by the former along with Emile Haynie, Jeff Bhasker and Mark Ronson, who had all previously co-produced the single "Locked Out of Heaven" for the same album. Atlantic Records serviced the track to Contemporary hit radio in the United States on September 10, 2013, as the fourth single from Unorthodox Jukebox. The official remix (G-Mix) of the song features American singers Pharrell Williams and R. Kelly, and was released in Canada and US on November 12. "Gorilla" is a midtempo rock and soft rock song with a power pop hook, epic guitars and a synth/percussion combination resembling a Phil Collins-esque. Its style has drawn comparisons towards Prince's 1984 single "Purple Rain".

The single received mixed to positive reviews from critics, who praised its early 1980s arena rock tendencies, but was criticized for its explicit lyrical content, which addresses the subject of making love like wild animals. The song charted moderately worldwide; it reached number 22 on the US Billboard Hot 100 and number 62 on the UK Singles Chart, being unable to achieve the same success of the previous singles. It was certified gold by the Recording Industry Association of America (RIAA), denoting digital downloads of over half a million copies in the US. Mars only performed "Gorilla" live at the 2013 MTV Video Music Awards, however the song was included on the set list of the 2013 Moonshine Jungle Tour as the final act, usually performed as an encore.
