"Back That Thing Up" is a song written by Jeremy Stover and Randy Houser and recorded by American country music artist Justin Moore, who released it in July 2008 as his debut single and the lead-off from his self titled debut album, which was released in August 2009. The song peaked at number 38 on the Billboard Hot Country Songs chart.

The song uses elements of country rap and country rock as well as sexual innuendo to describe a girl who is handling equipment on the farm (e.g. "Throw it in reverse, let Daddy load it up").

Kevin John Coyne of Country Universe gave the song a B- and stated that he would be "lying if [he] said [he] wasn't disappointed that this isn't a countrified version of the Juvenile hit. Alas, it's just a hillbilly rave-up that finds a country boy trying to get a city girl used to farm life, using backing up a truck as an awkward sexual metaphor" and that Moore "throws himself fully into the lyric like he was Joe Diffie singing a mid-1990's novelty number".

The music video was directed by Wes Edwards and premiered in July 2008.

This song debuted at number 55 on the Billboard Hot Country Songs chart for the week of August 23, 2008 and peaked at number 38 four months later.
