Knoxville was born Philip John Clapp in Knoxville, Tennessee, on March 11, 1971, the son of Sunday school teacher Lemoyne (Houck) and car and tire salesman Philip Clapp. He has two older sisters. Knoxville has compared his father to Dr Jekyll and Mr Hyde: "when he's not drunk, he was amazing, super funny. But when he was drinking it was total hell." Hanging out in his father's tire store, Knoxville would watch his dad play pranks on the "crazy characters" who worked for him. When he was fourteen, his cousin, singer-songwriter Roger Alan Wade, gave him a copy of Jack Kerouac's book On the Road. He credits this with sparking his interest in acting. After reading about Air Force researcher John Stapp, who conducted an experiment on himself to determine how much force a human body could withstand, Knoxville sympathized with the feeling Stapp termed "survival euphoria". Knoxville described it as a feeling after adrenaline that makes him desire even greater risk. Knoxville attended South-Young High School (now South-Doyle High School) in Knoxville, where he played on the baseball team and was named All-Knoxville Interscholastic League Honorable Mention. He also played in the Knoxville Area All Star game as a pitcher. After graduating in 1989, he moved to California to become an actor. He began appearing in commercials and as an extra, including a job as Keanu Reeves's stand-in on the 1992 Francis Ford Coppola film Bram Stoker's Dracula. When the breakthrough role he sought eluded him, he decided to create his own opportunities by writing and pitching article ideas to various magazines. An idea to test self-defense equipment on himself captured the interest of Jeff Tremaine's skateboarding magazine Big Brother, and the stunts were filmed and included in Big Brother "Number Two" video.

The show is directed by Jeff Tremaine, who produced a pilot that used footage from Big Brother and Bam Margera's CKY videos. With help from Tremaine's friend, film director Spike Jonze, they pitched a series to various networks. A deal was made with MTV and Jackass was born. He starred in Jackass: The Movie (2002), Jackass Number Two (2006), Jackass 2.5 (2007), Jackass 3D (2010), Jackass 3.5 (2011), Jackass Forever (2022), Jackass 4.5 (2022), and Jackass: Best and Last (2026) It will also be the last Jackass film.

Prior to Jackass premiering on MTV, Knoxville and company turned down an offer to perform their stunts for Saturday Night Live on a weekly basis, though Knoxville later hosted a 2005 episode of the show.

Knoxville's original leading role debut was set to be a holiday comedy released in late 2001 named The Tree but the project never came to fruition. Knoxville has been in several feature films, such as The Dukes of Hazzard (2005) and playing a two-headed alien in Men in Black II (2002).

In May 2014, Knoxville (along with Jackass Executive Producer/H.M.F.I.C. Derek Freda) formally announced the formation of a new production company called 'Hello Junior', which will continue Knoxville's now-longstanding relationship with Paramount Pictures, who have signed an exclusive two-year first-look deal with Knoxville and 'Hello Junior' in the wake of the massive success of Bad Grandpa in late 2013. Knoxville was quoted as saying, "I am over the damn moon about continuing an amazing partnership with Paramount Pictures. I have many more films to make and bones to break. I am glad I will be doing it for Paramount."

On February 4, 2009, Knoxville explained on The Howard Stern Show that he tore his urethra during a stunt for Jackass Presents: Mat Hoffman's Tribute to Evel Knievel (2008), describing how he had to flush it twice daily. He said this was done by "sticking a tube into [his] penis all the way up to [his] bladder", a practice known as urinary catheterization. He said the process prevented scar tissue from forming and that he performed the procedure "twice a day for three and a half years" after the injury. While filming the prank show The Prank Panel in December 2022, Knoxville was sued by handyman Khalil Khan, who alleged that he was subjected to a "terrifying ordeal" after signing up for a job on TaskRabbit.
