"Show Your Hand" is a song by Welsh rock band Super Furry Animals and was the first single from their 2007 album, Hey Venus!. The single was made available for download on 16 July 2007 as an iTunes exclusive and was later released in physical formats on 13 August in the UK. The track failed to penetrate the UK singles chart's Top 40, peaking at #46.

According to lead singer Gruff Rhys the track is "a song about gambling" and was originally going to be left off Hey Venus! for being "too generic" before Rough Trade boss Geoff Travis persuaded the band to reconsider their decision. Critical reaction to the track was mixed with some reviewers claiming "Show Your Hand" was "ponderously mature" and "more like the generic pop songs one would find on the radio" while others hailed the track as "classic Furries".

Unlike the two other singles taken from Hey Venus!, "Run-Away" and "The Gift That Keeps Giving", no music video was produced for "Show Your Hand".

In an interview with Pitchfork Media given before the release of Hey Venus!, singer Gruff Rhys claimed "Show Your Hand" was "a song about gambling. There's lots of card-playing going on in the Super Furry Animals [tour bus], which may have [had] a slight influence on the subject matter". Rhys went on to state that the song was initially left off Hey Venus! for being "too generic":

A combination of pressure from Rough Trade's Geoff Travis and Jeannette Lee ("Where's that song gone? That's our favorite song!") and the addition of a French horn part, written by Cian Ciaran, resulted in the song finally taking its place on the record. Although the majority of the track was recorded at Miraval Studios, France along with the rest of Hey Venus!, additional recording also took place with Chris Shaw who mixed the album. According to Cian Ciaran both b-sides to "Show Your Hand", namely "Aluminium Illuminati" and "Never More", were originally recorded during sessions for 2003's Phantom Power although "Aluminium Illuminati" was mentioned as a working title as early as May 2000 in connection with 2001's Rings Around the World album.
