"Walk on Water" is a song by American rapper Eminem and produced by Rick Rubin and Skylar Grey. The song features American singer Beyoncé, and was released on November 10, 2017, as the first single from Eminem's ninth studio album Revival.

The song started as a hook written by Skylar Grey. Eminem came across the hook when he was working with Rick Rubin and became enamored with the lyrics. Previously Rubin and Eminem had been discussing the phenomenon of mumble rap, specifically Eminem's frustration with its mainstream popularity, and the hook served as a vehicle for him to vent them. Rubin subsequently played the song for Jay-Z, who was then able to get his wife, Beyoncé, to sing the chorus. Upon the release of the single, Grey tweeted "This is the song I've been trying to write since age 6. Every time I wrote a song I hoped it would be this good. I am truly proud of everything I've created, but this is the one."

On November 8, 2017, Eminem tweeted a picture of a doctor's prescription note with the words "'Walk on Water', take as needed" written on it. This has caused speculation that the first single will be titled "Walk on Water". The fake doctor's note was labeled with the logo for Revival. On November 9, Paul Rosenberg shared a video on Instagram which showcased Trevor the spokesperson for the Revival campaign stating that "you will be able to Walk on Water with Revival at noon EST", confirming the song. As of November 15, 2017, the official "Walk on Water" audio YouTube video had garnered over 20 million views.

The song was first performed, by Eminem, at the 2017 MTV Europe Music Awards on November 12, featuring Skylar Grey.
