"Rock n Roll" is a song by Canadian recording artist Avril Lavigne. It was released as the second single from her self-titled fifth studio album by Sony Music Entertainment on August 23, 2013. The song was written by Lavigne, David Hodges, Chad Kroeger, Jacob Kasher Hindlin, Rickard B. Göransson and Peter Svensson and was produced by Peter Svensson.

"Rock n Roll" is an upbeat pop punk song, and lyrically it is a declaration of rebellion on which the singer puts up her "middle finger to the sky" to "let 'em know that she's still rock and roll," refusing to behave like an adult. The song received a critical praise from music critics, and was highlighted as one of the standout tracks on the album.

"Rock n Roll" performed moderately on the charts, reaching number one in South Korea and Taiwan, and number five in Japan, respectively. The song failed to make impact elsewhere, peaking at number 37 in Canada and number 91 on the US Billboard Hot 100 chart. The music video directed by Chris Marrs Piliero shows Lavigne in full combat mode, conspiring with Danica McKellar (playing a character called Winnie Cooperre) in an attempt to "save rock and roll".

After "Here's to Never Growing Up", Lavigne announced that "Rock n Roll" will be the second single from her "self-titled fifth studio album", asking to her fans on her Twitter page, on 18 July 2013, to unlock the single's cover art. After her fans tweeted so much and a consistent worldwide trending topic, Lavigne released the cover art for "Rock N Roll" and gave her fans an exclusive listen to the song, uploading the full audio onto her YouTube account.
