"I Wanna Rock" is a song written and composed by Dee Snider and performed by his band Twisted Sister. It was released on the 1984 album Stay Hungry. In 2009, it was named the 17th VH1 Greatest Hard Rock Songs by VH1.

Like the earlier "We're Not Gonna Take It", the video features actor Mark Metcalf, best known as the sadistic Douglas C. Neidermeyer from the movie National Lampoon's "Animal House" released in 1978. Here, he plays a ferocious teacher who harasses a student for drawing the Twisted Sister logo on his notebook, shrieking: "What kind of a man desecrates a defenseless textbook?!? I've got a good mind to slap your fat face!!" (This echoed his line from National Lampoon's "Animal House:" "What kind of man hits a defenseless animal [a misbehaving horse]? I've got a good mind to smash your fat face in!") In conclusion to a rant which begins with that yelled-out question, he shrieks his question from the "We're Not Gonna Take It" video, "WHAT DO YOU WANT TO DO WITH YOUR LIFE???" The student answers with the first line of the song, "I WANNA ROCK!!!" Thereupon he and four of his classmates are instantly "transformed into" (actually replaced by) Twisted Sister's five members. After the vicious teacher's repeated attempts to stop his rock-loving students not only fail but also backfire on him, he crawls into the principal's office, only to be confronted by the principal, played by Stephen Furst, a.k.a. Kent "Flounder" Dorfman from National Lampoon's "Animal House." Furst even gets to reprise one of his big lines from the movie: "Oh boy, is this great!" He delivers it as he sprays water from a seltzer bottle at the mean teacher. (In the climactic homecoming-parade sequence of the actual film, Metcalf's Niedermeyer shot out the seltzer bottle just before Furst's Dorfman could do this last.)

"I Wanna Rock" is subject to numerous media appearances, including:
