"Ayo" is a song by American singer Chris Brown and American rapper Tyga, released as the lead single from their collaboration album Fan of a Fan: The Album. It was produced by Nic Nac and Mark Kragen, whom the former Chris previously worked with on "Loyal".

An accompanying music video was directed by Colin Tilley and filmed in Los Angeles, California. The video features various scenes of Brown and Tyga competing with one another to show off their riches and ends with them drag racing Lamborghinis. It also features cameo appearances by comedian Mike Epps and the dance duo Les Twins. The song was included on the set list of their 2015 Between the Sheets Tour with Trey Songz.

"Ayo" was written by Chris Brown and Tyga (real name Michael Stevenson) together with the track's producers Nic Nac (real name Nicholas Balding) and Mark Kragen. On November 14, 2014 Tyga announced via Twitter that the lead single from his and Brown's long-awaited Fan of a Fan: The Album would be released in one week. The single was expected to be "Nothin Like Me" featuring Ty Dolla $ign and produced by DJ Mustard, but the album was delayed and the decision was made to release "Ayo" as the lead single instead. During an interview with Power 106 on December 5, 2014 Brown announced a January release for the song and expressed his excitement, stating, “We already got it locked and loaded. Nic Nac produced it; it’s crazy. It’s one of them ones. We just gonna have fun, man.” An early preview of “Ayo” was released on SoundCloud on December 17, 2014 after Brown tweeted, “Who is ready for this CHRIS BROWN/TYGA ALBUM??? Got a surprise for the fans coming!”. Three weeks later, the song officially premiered on iTunes on January 6, 2015.
