Anna Christie is a play in four acts by Eugene O'Neill. It made its Broadway debut at the Vanderbilt Theatre on November 2, 1921. O'Neill received the 1922 Pulitzer Prize for Drama for this work. According to historian Paul Avrich, the original of Anna Christie was Christine Ell, an anarchist cook in Greenwich Village, who was the lover of Edward Mylius, a Belgian-born radical living in England who libeled the British king George V.

Eugene Gladstone O'Neill was an American playwright. His poetically titled plays were among the first to introduce into the U.S. the drama techniques of realism, earlier associated with Chekhov, Ibsen, and Strindberg. The tragedy Long Day's Journey into Night is often included on lists of the finest U.S. plays in the 20th century, alongside Tennessee Williams's A Streetcar Named Desire and Arthur Miller's Death of a Salesman. He was awarded the 1936 Nobel Prize in Literature. O'Neill is also the only playwright to win four Pulitzer Prizes for Drama.
