"Back That Thing Up" is a song written by Jeremy Stover and Randy Houser, and recorded by American country music artist Justin Moore.

[4] It got a "thumbs up" review from The 9513's Jim Malec, who noted that the lyrics "separated (at least semantically) the inherent innuendo from the song's story itself as in the final verse, he negates the song's innuendo by singing the lyric 'Ain't no time to play'.

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-1990s novelty number".

[5] In 2017, Billboard contributor Chuck Dauphin put "Back That Thing Up" at number ten on his top 10 list of Moore's best songs.

[6] The music video was directed by Wes Edwards and premiered in June 2009.
