Anastasia is a musical play with music and lyrics by Lynn Ahrens and Stephen Flaherty, and a book by Terrence McNally. Based on the 1997 animated film of the same name, the musical adapts the legend of Grand Duchess Anastasia Nikolaevna of Russia, who could have escaped the execution of her family. Years later, an amnesiac orphan named Anya hopes to find some trace of her family by siding with two con men who wish to take advantage of her likeness to the Grand Duchess.

After completing a pre-Broadway run in Hartford, Connecticut, the show premiered on Broadway at the Broadhurst Theatre in April 2017, and since then it has spawned multiple productions worldwide.
