Diamond Eyes is the sixth album by American Alternative metal band Deftones, released worldwide on May 4, 2010 through Warner Bros. and Reprise Records. An album tentatively titled Eros was originally intended to be their sixth full-length release and follow up to Saturday Night Wrist (2006), but was not released due to bassist Chi Cheng entering a coma after a serious car accident that occurred in November 2008. The release of Eros was put on hold in favor of Diamond Eyes in June 2009. Former Quicksand bass player, Sergio Vega is featured on the album in substitution for Cheng.

It was the band's highest charting album on the Billboard 200 since their album, Deftones. Diamond Eyes debuted at Number 6, while the previous Saturday Night Wrist debuted at Number 10.
