Next to Normal (stylized in all lowercase) is a 2008 American rock musical with book and lyrics by Brian Yorkey and music by Tom Kitt. The story centers on a mother who struggles with worsening bipolar disorder and the effects that managing her illness has on her family. The musical addresses grief, depression, suicide, drug abuse, ethics in modern psychiatry, and the underbelly of suburban life.

Before its Off-Broadway debut, Next to Normal received several workshop performances and won the Outer Critics Circle Award for Outstanding New Score and received Drama Desk Awards nominations for Outstanding Actress (Alice Ripley) and Outstanding Score. After its Off-Broadway run, the show played from November 2008 to January 2009 at the Arena Stage while the theater was in its temporary venue in Virginia.

The musical opened on Broadway in April 2009. It was nominated for eleven Tony Awards that year and won three: Best Original Score, Best Orchestration, and Best Performance by a Leading Actress in a Musical for Alice Ripley. It also won the 2010 Pulitzer Prize for Drama, becoming the eighth musical in history to receive the honor. In awarding the prize to Kitt and Yorkey, the Pulitzer Board called the show "a powerful rock musical that grapples with mental illness in a suburban family and expands the scope of subject matter for musicals."

The first US tour launched in November 2010, with Alice Ripley reprising her Broadway role; the tour concluded in July 2011. The Broadway production closed on January 16, 2011, after 20 previews and 734 regular performances. There have been numerous international productions.
