Our American Cousin is a three-act play by English playwright Tom Taylor. It is a farce featuring awkward, boorish American Asa Trenchard, who is introduced to his aristocratic English relatives when he goes to England to claim the family estate. The play premiered with great success at Laura Keene's Theatre in New York City in 1858, with Laura Keene in the cast, the title character played by Joseph Jefferson, and Edward Askew Sothern playing Lord Dundreary. The play's long-running London production in 1861 was also successful.

Tom Taylor was an English dramatist, critic, biographer, public servant, and editor of Punch magazine. Taylor had a brief academic career, holding the professorship of English literature and language at University College, London in the 1840s, after which he practised law and became a civil servant. At the same time he became a journalist, most prominently as a contributor to, and eventually editor of Punch.
