"Break" is the first single from Three Days Grace's third album, Life Starts Now. It was released three weeks before Life Starts Now hit stores.

On August 31, 2009, the song made its North American radio debut on Ottawa, Ontario's CKQB-FM (Virgin Radio 106.9). The song became available in the iTunes Store on September 4, 2009.

In Billboard magazine, it charted at number 73 on the Billboard Hot 100, number one on the Rock Songs chart, number one on the Mainstream Rock Tracks chart, number four on the Alternative Songs chart, and number 26 on the Canadian Hot 100. "Break" maintained a presence on the Billboard Rock Songs and Mainstream Rock Tracks charts for twelve, and eleven, weeks respectively. Since this track's release, no subsequent Three Days Grace single has charted on the Billboard Hot 100.

As of February 21, 2010, the single has sold 359,461 units.

While being interviewed by the Peterborough Examiner, bass guitarist Brad Walst stated that "[the song] 'Break' is about breaking away from bad influences." Additionally, in an interview with TheDeadbolt.com, lead guitarist Barry Stock explained the meaning behind "Break":

"It's really just about if you don't like the situation you're in or what's going on around you, it's entirely up to you to break out of it. That's it. It's pretty much just breaking out and letting loose. You don't have to be stuck in whatever it is you're dealing with. Whether it's good or bad, it's your choice to make a change."

On September 11, Three Days Grace announced the music video for "Break" would debut on Yahoo! Music on September 14, 2009. The music video, directed by P. R. Brown, begins with the band members entering separate rooms that match their clothes' colors (Adam wearing white, Neil wearing black, Brad wearing gray, and Barry wearing pink), and shows four balls, matching the aforementioned colors, in a pendulum-like state. The beginning of the track "Someone Who Cares" serves as an intro for the music video version of the song. The band begins to perform their parts in these separate rooms as giant fans appear and begin to operate. As the song progresses, floating balls are pulled through the fans and thus travel in a circle that leaves them stained with the color of the bandmate to their left (Adam with pink, Neil with white, Brad with black, and Barry with gray). The song ends with them exiting down a hall, the four paint balls following them.
