"Rock This Country!" is a song co-written and recorded by Canadian country music singer Shania Twain. It was the tenth single released to country radio in January 2000 from her album Come on Over. Written by Mutt Lange and Twain, "Rock This Country!" was released to North American country radio stations in late 1999. With no promotional performances or CD single, the song was the lowest charting single at country radio from the album.

On "Rock This Country!" Twain said the song is "a very live, fast-driving song. We wrote that one on the beach in Florida. I had had the title a long time". "Rock This Country!" became the closing song each night on both the Come on Over Tour and the Up! Tour. It is the only song to stay the same on both the original and international versions of Come on Over. Al Gore used "Rock This Country!" as the theme song to his 2000 Presidential Campaign.Hillary Clinton selected "Rock This Country!" as a candidate theme song for her 2008 Presidential campaign.

Shania performs a live acoustic version of the song during her "Still the One" show in Las Vegas.

Her 2015 tour was named after this song.

Billboard applauded the song saying it "pushes all the buttons that should make it a natural for today's young country audience" and calling it "a rollicking, fiddle-laced number that should become a weekend anthem".

The music video for "Rock This Country!" was taken directly from Twain's 1999 Come on Over special from Dallas. It was filmed on November 25, 1999 and released on December 23, 1999. Directing credit is given to Larry Jordan. This video was the second consecutive live video released from the Come on Over album, and third overall, as both "Honey, I'm Home" and "Come on Over" were issued live videos. The video is known for Twain's "space-age" looking outfit. It is available on Twain's DVD The Platinum Collection.
