"My Own Soul's Warning" is a song by American rock band the Killers from their sixth studio album, Imploding the Mirage (2020). It was released on June 17, 2020, as the album's second single.

Album lead track, "My Own Soul's Warning" was written near the end of the Imploding the Mirage sessions, when frontman Brandon Flowers was worried that the album didn't have a single and he started to panic. It was the final song written for the album.

The band struggled to get the right mix for the song, going through nearly 90 mixes of it, with Flowers describing it as a “stubborn son of a bitch.”

Writing about the song for Apple Music, Flowers said that the song was about "repentance", which he acknowledged is "not a typical subject in a pop or rock song". He said he wanted to "write something that was meaningful to myself and that felt like it was going to transcend and resonate with a lot of people in a stadium or inside their headphones."

It is Flowers' favourite song on the Imploding the Mirage album.

The band leaked the intro to the song during a live stream on Instagram in April 2020, two months before it was released.

Two music videos have been made for the song.
