"Show Yourself" is a single by American progressive metal band Mastodon, off of their studio album Emperor of Sand. It peaked at number 4 on the Billboard Mainstream Rock Songs chart in 2017, making it their highest charting song to date.

The guitar riff for the song was first created by band guitarist Bill Kelliher while creating a collection of riffs when on tour in 2016. With most of the band's members alternating vocal duties on the band's song, vocals for "Show Yourself" were handled by drummer Brann Dailor. Dailor was initially hesitant to sing on the track, personally not liking the guitar riff, referring to it as "too easy", though he later changed his mind on it. Dailor reflected on the track's simplicity, stating:

I guess there's a part of me that doesn't want to let people down, and I thought some of our most critical fans would frown on this version of us, so I wanted to sidestep it. But Troy [Sanders] was really into it, so that started to sway me. And when I came up with the vocal pattern, it was really obvious and kinda sounded like Queens of the Stone Age to me. It was like, 'Oh, we're wearing a Queens costume.' And I liked it. And once the album came into focus, it was like, 'We need something like this.' It's like an oasis in a really dense record.

The song was released as the second single from their album Emperor of Sand, on February 3, 2017. The band performed the track live on Jimmy Kimmel Live! on April 3, 2017.

The song comes from the band's seventh studio album, Emperor of Sand, a concept album which explores heavy themes such as humanity's existence and limited mortality through the scenario of a person being diagnosed with cancer and going through chemotherapy. The song lyrically plays into the same concepts, with lines such as You're not as safe as far as I can tell, and I can tell /Only you can save yourself/ Soon this will all be a distant memory/ Or could this dream be real at all?" While the band is known for music that is progressive rock and complicated in structure, the song relatively straightforward, with Rolling Stone describing the track as "relatively stripped-down, melodic and direct. 'Show Yourself' erupts from a straight-ahead riff layered with spasms of wild guitar from Brent Hinds. The song features a guitar solo by Hinds as well.Stereogum noted that, while the band's first single, "Sultan Curse" contained the atmosphere of their earlier work, "Show Yourself" instead sounded like the "grungy chug-brood more in line with the work that the band has been doing in recent years". Dailor summed up the song as "super-poppy” by Mastodon standards, while still dealing with the same themes of death and sadness".
