Broken Social Scene is the third studio album by the band of the same name, released on October 4, 2005. The album was originally to be titled Windsurfing Nation。
The original artwork was to be a cartoon rendition of Pangaea, which was later scrapped in favor of the current artwork drawn by lead singer Kevin Drew.

In addition to the musicians who contributed to the band's prior release You Forgot It in People, new contributors on Broken Social Scene include k-os, Jason Tait (The Weakerthans) and Murray Lightburn (The Dears).

The initial domestic pressings of the album were issued with a seven-track bonus EP, EP To Be You and Me, a play on Marlo Thomas' children's record album Free to Be… You and Me. The Japanese release is still issued with the EP. The vinyl pressing was released on two records, the first three sides being the album and the fourth being the EP.

The song "Ibi Dreams of Pavement (A Better Day)" refers to Canadian novelist Ibi Kaslik, a friend of the band.
