Leader of the Pack is a 1984 American jukebox musical based on the life and music of singer/songwriter Ellie Greenwich. The musical tells the story of Greenwich's career and personal life from the 1950s to the 1980s, using songs written or co-written by Greenwich, along with Jeff Barry, Phil Spector, George "Shadow" Morton, Jeff Kent, and Ellen Foley. The musical was based on an original concept by Melanie Mintz, and the book was written by Anne Beatts, with additional material by Jack Heifner.

A jukebox musical is a stage musical or musical film in which a majority of the songs are well-known popular music songs, rather than original music.
