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. It was given its first performance at the Teatro Carolino, in Palermo, on 11 February 1843.

The opera was greeted with considerable acclaim at its creation. 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.^[1]

Between March and May 2012, the opera was performed at the City Theater of Giessen in Germany. ^[2]

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. She has been raised and is now betrothed to the adoring Ernesto Malcolm, a commoner. Gualtiero Churchill, the Lord Chancellor, wants to protect the Queen by bringing Riccardo down, so he tells the Queen of Talbot's duplicity, and also reveals his knowledge that Clotilde is actually heir to the Talbot name. The Queen condemns Fenimoore to death but repents and orders Clotilde to help release him. However, to the dismay of the Queen, Churchill sees to it that the execution is carried out.
