Maria, regina d'Inghilterra (Mary Tudor, Queen of England) is an Italian opera in three acts, composed by Giovanni Pacini from a libretto by Leopoldo Tarantini, which was based on the 1833 play Marie Tudor by Victor Hugo.

After a decade or so, it lost its popularity and disappeared from the stage until its revival by Opera Rara at the Bloomsbury Theatre in London as part of the Camden Festival on 23 March 1983.

[2] Odyssey Opera mounted a fully staged production on 1 and 3 November 2019 at the Huntington Theater in Boston.

[3] Mary I of England is infatuated with the Scottish adventurer Riccardo Fenimoore, whom she has ennobled as Lord Talbot, but he is unfaithful to her having seduced the foundling Clotilde, who is the only surviving child of the late Earl of Talbot.

The Queen condemns Fenimoore to death but repents and orders Clotilde to help release him.
