Underclass Hero is the fourth studio album by Canadian rock band Sum 41. It is the first of two albums by the band recorded without guitarist Dave "Brownsound" Baksh since he left a year earlier to focus on Brown Brigade. It was first released on July 18, 2007, in Japan by Island Records and distributed worldwide by Aquarius Records, the band's final album on the label. In comparison to the heavy metal-inspired punk style of their previous album Chuck (2004), Underclass Hero marked a return to the band’s pop-punk sound.
The album was a commercial success, peaking at number 1 on the Canadian Albums Chart and at number 7 on the US Billboard 200, becoming the band’s highest-charting album to date. It received generally mixed reviews from critics, with some praising its songwriting, lyrics and production, while others found it to be too long, melodramatic, and derivative.
