"Get on Your Boots" is the lead single from U2's 2009 album, No Line on the Horizon. The song was made available digitally on 23 January 2009. The physical format was released on 16 February. The video received its premiere on 6 February 2009.

 bootlegged, early version of the song was partly released to YouTube during the band's recording sessions at the French resort of Èze. The poor quality version was subsequently removed from the site at the behest of the band's record label, Universal Records. Media reports in August 2008 originally referred to the song by the title "Sexy Boots", and later as "Get Your Boots On". It was later revised to "Get on Your Boots".

"Get on Your Boots" was scheduled to receive its world radio premiere on The Colm & Jim-Jim Breakfast Show on the radio station RTÉ 2fm at 8:10 on 19 January 2009 by the band's long-time friend and favoured disc-jockey Dave Fanning. However, after a nearly 30 second sample of the song was leaked onto the Internet, the song was made available in the iTunes Store for purchase (an hour before its first play by Fanning) and the band decided to begin streaming the song on U2.com later that day.
