Light Grenades is the sixth album by Incubus, released on November 28, 2006 (see 2006 in music). The album sold 229,000 copies during its first week of release worldwide, mostly in the United States.

Light Grenades debuted at #1 on the Billboard 200, selling 165,000 copies in the U.S. in its first week; it is the band's first number one album. However, Light Grenades also holds the dubious record of the biggest drop from #1 in chart history, falling from #1 to #37 in its second week on the Billboard 200 Albums chart and breaking the record set by Marilyn Manson's The Golden Age of Grotesque, which fell from #1 to #21 in 2003. The album has since gone gold in the US. As of July 11, 2007, it has sold 645,000 copies in the US.
