Our American Cousin is a 2008 opera in three acts by American composer Eric Sawyer with libretto by poet John Shoptaw. The opera depicts the assassination of Abraham Lincoln from the standpoint of the actors presenting Tom Taylor's play of the same name at Ford's Theatre at the end of the American Civil War. It aims to offer something new in the realm of American contemporary opera, an American myth told in an unfamiliar way, with both poetic and musical language drawing from the past but refracted through the present.
The opera's narrative is the collaborative invention of Shoptaw and Sawyer, freely imagined within the framework of the documented historical event and adapted plot of the original comedy. Its three acts comprise the backstage events prior to the play, the play itself, and the rupture of the stage drama by the assassination and its aftermath.
