Who wrote the book for the Broadway musical Avenue Q?

Jeff Whitty wrote the book for the Broadway musical Avenue Q.

Avenue Q opened on Broadway at the Golden Theatre on July 31, 2003. Whitty wrote the book, while Robert Lopez and Jeff Marx wrote the music and lyrics. The musical uses human actors alongside puppets to tell a comic story about young adults trying to find work, relationships, and direction in New York City.

The production won the 2004 Tony Award for Best Musical, along with awards for its original score and book. Its puppetry was influenced by television puppet traditions but was designed for a specifically theatrical setting, with performers often remaining visible while operating the characters.

Avenue Q is sometimes misidentified as a musical written entirely by Robert Lopez, because Lopez later became widely known for other major projects. He and Marx created the songs, but Whitty was the book writer. The show’s adult humor and themes distinguish it from children’s puppet entertainment.
