Jimmy Thudpucker is a fictional character in the comic strip Doonesbury, created by Garry Trudeau.

He is generally seen as a combination of Bob Dylan and John Denver (and to some extent, Loudon Wainwright III), and became a rock star in the seventies, when he was only 19.

He even wrote a song about Doonesbury character Ginny Slade to help her raise money for her campaign for free, because he agreed with her politics.

Jimmy supports file sharing, and firmly believes that in the future artists will make a modest living by touring because the recording industry will collapse and all music will be free.

James Allen Brewer, an actor ("Ryan and Sean's Not So Excellent Adventure"), producer ("Simply Sondheim – A 75th Birthday Salute"), and singer/songwriter co-wrote and sang, in character, on the single "Ginny's Song," released by Warner Bros.
