Horror films have always reflected their audiences' fears and anxieties. In the United States, the 2000s were a decade full of change in response to the 9/11 terrorist attacks, the contested presidential election of 2000, and the wars in Iraq and Afghanistan. These social and political changes, as well as the influences of Japanese horror and New French extremism, had a profound effect on American horror filmmaking during the 2000s.

This filmography covers more than 300 horror films released in America from 2000 through 2009, including such popular forms as found footage, torture porn, and remakes.
