Marino Faliero, Doge of Venice is a blank verse tragedy in five acts by Lord Byron, published and first performed in 1821.

Marino Faliero, recently elected Doge of Venice, offends one of the chief officers of state, Michele Steno.

Faliero is so outraged by this, as he believes it to be an inadequate punishment for such an affront to the ruling Doge, that he secretly joins in the conspiracy of a group of malcontents to abolish the constitution of Venice, thinking thereby to gain revenge on his enemies.

The reaction from both audiences and critics was lukewarm; perhaps, as Byron thought, because of the play's neoclassical form and lack of sensationalism and love interest.

[8][9][10] The subject of Eugène Delacroix' painting The Execution of the Doge Marino Faliero (1825–26), now in the Wallace Collection in London, was suggested by Byron's play.
