Little Shop of Horrors is a horror comedy rock musical with music by Alan Menken and lyrics and a book by Howard Ashman. The story follows a hapless florist shop worker who raises a plant that feeds on human blood and flesh. The musical is loosely based on the low-budget 1960 black comedy film The Little Shop of Horrors. The music, composed by Menken in the style of early 1960s rock and roll, doo-wop and early Motown, includes several well-known tunes, including the title song, "Skid Row (Downtown)", "Somewhere That's Green", and "Suddenly, Seymour".

The musical premiered off-off-Broadway in 1982 before moving to the Orpheum Theatre off-Broadway, where it had a five-year run. It later received numerous productions in the U.S. and abroad, and a subsequent Broadway production. In part because of its small cast, it has become popular with community theatre, school and other amateur groups. The musical was also made into a 1986 film of the same name, directed by Frank Oz.
