The Duchess of Padua is a five-act tragedy by Oscar Wilde, set in Padua and written in blank verse. It was written for the actress Mary Anderson in early 1883 while Wilde was in Paris. After she turned it down, it was abandoned until its first performance at the Broadway Theatre in New York City under the title Guido Ferranti on 26 January 1891, where it ran for three weeks. It has been rarely revived or studied.

Oscar Fingal O'Fflahertie Wills Wilde was an Irish poet and playwright. After writing in different forms throughout the 1880s, he became one of the most popular playwrights in London in the early 1890s. He is best remembered for his epigrams and plays, his novel The Picture of Dorian Gray, and his criminal conviction for gross indecency for homosexual acts.
