The System Has Failed is the tenth studio album by American thrash metal band Megadeth, released on September 14, 2004. It was the band's second and final studio album to be distributed by Sanctuary Records.

The album features former Megadeth member Chris Poland (guitar), who previously performed on Killing Is My Business... and Business Is Good! (1985) and Peace Sells... but Who's Buying? (1986), and session musicians Vinnie Colaiuta (drums) and Jimmie Lee Sloas (bass).
