"Fallout" is a song recorded by Canadian pop punk band Marianas Trench for their third studio album, Ever After (2011).

[1] The song has peaked in the Top 40 on the Billboard Canadian Hot 100 and been certified Gold by Music Canada.

Its instrumentation consists primarily of drums and guitar, while its "krushed groove" and vocal arrangement have been described by CBC Music as having an R&B influence.

"[3] Catherine Yi at Pupfresh felt that "Fallout" was a "catchy, pleasing song" with strong radio potential, but that it offered too little musical or lyrically variation throughout.

[7] The video starts with Josh Ramsay breaking up with his girlfriend (Darla Taylor) in an open minefield.
