Ryan Matthew Dunn (June 11, 1977 - June 20, 2011) was an American stunt performer, television personality, comedian, actor, writer, musician, and one of the stars of the MTV reality stunt show Jackass. Dunn rose to fame in the late 1990s as a member of the CKY Crew with his long-time friend, Bam Margera, for their extreme stunts and pranks recorded on camera, which led to the rise of Jackass. Dunn also hosted Homewrecker and Proving Ground, and appeared in the feature films Blonde Ambition and Street Dreams, as well as in Margera's films Haggard and Minghags. Dunn died in a car crash in 2011, on the 10th anniversary of Jackass.

Dunn took part in the characteristic stunts that made Jackass famous, and featured in all three released films, Jackass: The Movie, Jackass Number Two and Jackass 3D.  In 2006, Dunn and Bam Margera participated in the Gumball 3000 road rally in Margera's Lamborghini Gallardo. He later went on a tour with Don Vito called "The Dunn and Vito Rock Tour" for which the DVD was released on March 20, 2007. Dunn and Margera again participated in the rally in 2008.  Bam Margera stated during a December 2, 2008, radio interview with Big O and Dukes of 106.7 WJFK-FM, that he and Dunn would be going to Italy to film Where the F*%# Are My Ancestors. That same month, Dunn appeared on the episode "Smut" of Law & Order: Special Victims Unit in December 2008. He is also featured in a movie called Street Dreams which was released in spring 2009. He co-starred along with Rob Dyrdek and Paul Rodriguez Jr. Dunn was also featured on a show with fellow Jackass star Bam Margera about them traveling through Europe in a Viva la Bam-like show called Bam's World Domination for Spike. He appeared in Jackass 3D, which was released on October 15, 2010.  Dunn co-hosted G4's Proving Ground along with Jessica Chobot, which made its premiere on June 14, 2011, six days before his death. However, according to a G4 spokesperson, the channel decided to postpone the airing of further episodes. The spokesperson added, "The show is off the schedule as of today until we discuss next steps." On June 27, G4 announced they would air the remaining episodes starting on July 19, 2011. At the time of his death, Dunn was working on the film Welcome to the Bates Motel. The film was later renamed The Bates Haunting and was released in 2013.
