Wayne's World is a 1992 American comedy film directed by Penelope Spheeris and starring Mike Myers in his film debut as Wayne Campbell and Dana Carvey as Garth Algar, hosts of the Aurora, Illinois-based Public-access television cable TV show Wayne's World. The film was adapted from a sketch of the same name on NBC's Saturday Night Live.

The film grossed US$121.6 million in its theatrical run, placing it as the tenth highest-grossing film of 1992 and the highest-grossing film ever based on a Saturday Night Live skit. It was directed by Penelope Spheeris, with Myers co-writing the script. It was filmed in 34 days.

Wayne's World was Myers' feature film debut. The film also featured Rob Lowe, Tia Carrere, Lara Flynn Boyle, Brian Doyle-Murray, Robert Patrick (spoofing his role in Terminator 2: Judgment Day), Chris Farley, Ed O'Neill, Ione Skye, Meat Loaf, and Alice Cooper.

Wayne's World received mostly positive reviews upon release and was commercially successful (unlike many Saturday Night Live-based films). It was followed by Wayne's World 2. In 1993, readers of Total Film magazine voted Wayne's World the 41st greatest comedy film of all time.

Wayne's World was originally a recurring sketch from the NBC television series Saturday Night Live. It evolved from a segment titled "Wayne's Power Minute" (1987?-88) on the CBC Television series It's Only Rock & Roll, as the main character first appeared in that show. The Saturday Night Live sketch spawned two films, and several catchphrases which have since entered the pop-culture lexicon. The sketch centered on a local Public-access television program in Aurora, Illinois, hosted by Wayne Campbell (Mike Myers, the same actor from "Wayne's Power Minute"), an enthusiastic and sardonic long-haired metalhead, and his timid and sometimes high-strung, yet equally metal-loving sidekick and best friend, Garth Algar (Dana Carvey) . Wayne lives with his parents and broadcasts his show "live" from the basement of their house every Friday evening at 10:30. The first "Wayne's World" sketch appeared in the 13th Saturday Night Live episode of 1988.

The "show" would open with Wayne and Garth singing the lyric to the opening theme, "Wayne's World! Wayne's World! Party time! Excellent!", accompanied by Wayne's frantic strumming of his guitar, and Garth drumming on his lap with drum sticks. The two would introduce themselves (Garth: "Party on, Wayne." Wayne: "Party on, Garth.") and then proceed to go into their various exploits, including discussions of their love of hard rock bands and "babes", as well as juvenile antics, such as the "Extreme Close-Up" (where a camera would zoom in on Wayne and Garth as they screamed) and tricking their unsuspecting guests into saying vulgar words. Garth would frequently get overexcited and lose control, to which Wayne would have to tell him, "Take your Ritalin."
