Fahrenhype 9/11 (stylized FahrenHYPE 9/11) is a 2004 documentary video made in response to Michael Moore's documentary Fahrenheit 9/11. Part of a large group of documentaries that began appearing in the mid-2000s as improved technology allowed anyone to quickly and affordably create movies, the video was created in 28 days and was narrated by Ron Silver. Dick Morris (who also receives a co-writing credit), appears frequently, and features interviews with various political figures, including David Frum, Georgia Democratic Senator Zell Miller, social and political commentator Ann Coulter, and former Democratic New York City mayor Ed Koch.

The movie was released with a companion book, on October 5, 2004, the same day that Fahrenheit 9/11 was released on home video.
