The Duchess of Padua is a play by Oscar Wilde. 

It is a five-act tragedy set in Padua and written in blank verse. It was written for the actress Mary Anderson in early 1883 while 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.
