Alex O'Neill, better known as Ayokay, is an American producer and DJ from Grosse Pointe, Michigan.

O'Neill attended high school with Mikael Temrowski, who would go on to perform under the name Quinn XCII; the pair worked together while both were college students at different universities in Michigan. Their 2016 single "Kings of Summer" was chosen by Ian Desmond, then a baseball player for the Texas Rangers, as his walk-up music, which increased the track's popularity and led to a record deal with Columbia.

O'Neill then moved to Los Angeles, releasing a full-length album, In the Shape of a Dream, which featured various artists including Jeremy Zucker, Quinn XCII, Nightly, Jenny Mayhem, Future Jr., and Katie Pearlman in 2018. He has had two hit singles on the Billboard Hot Dance/Electronic Songs Chart: "Kings of Summer" with Quinn XCII, which reached #18 in 2016, and "The Shine" with Chelsea Cutler, which reached #50 in 2017. He released his second album Digital Dreamscape in 2022.
