''Chuck'' is the third studio album from Canadian rock band Sum 41. The album was released on October 12, 2004. It is the band's last album to feature lead guitarist Dave Baksh. He left the band on May 11, 2006 to pursue his own career with his new band Brown Brigade.

The album is named after a UN peacekeeper Chuck Pelletier, who was in the Democratic Republic of the Congo, where the band was filming a documentary for ''War Child Canada''. Fighting broke out during the filming and Chuck helped the band evacuate from their hotel during the fighting (Chuck was staying in the same hotel during that time). The album received positive reviews from critics, and it won a Juno Award in 2005 for ''Best Rock Album of the Year''. The album was certified platinum in Canada and gold in the United States.

In an online poll, "No Reason" was voted the favorite song, with "We're All to Blame" coming in second. - Wikipedia
