You're a Good Man, Charlie Brown is a 1967 musical with music and lyrics by Clark Gesner and (in a 1999 revision) Andrew Lippa. It is based on the characters created by cartoonist Charles M. Schulz in his comic strip Peanuts. The musical has been a popular choice for amateur theatre productions because of its small cast and simple staging

John Gordon was credited with the book of the show, but according to Gesner's foreword in the published script, "John Gordon" is a collective pseudonym that covers Gesner, the cast members, and the production staff, all of whom worked together to assemble the script. The Guide to Musical Theatre notes that "John Gordon is a pseudonym for the staff and cast of the show. The original cast included Bob Balaban, Gary Burghoff, Bill Hinnant, Skip Hinnant, Karen Johnson and Reva Rose."
