The Black Duchess (also Mourning Portrait of the Duchess of Alba or simply Portrait of the Duchess of Alba) is a 1797 oil-on-canvas painting by Spanish painter Francisco Goya. In the painting, María Cayetana de Silva, 13th Duchess of Alba (the Duchess) is thirty-five years old. It is a companion piece to the more chaste The White Duchess, completed two years earlier. In this work, de Silva is dressed in low cut Maja clothing, probably she agreed to this depiction as it might show her as a "woman of the people". As of 2012 the painting is kept at the New York Hispanic Society, operated by the Hispanic Society of America.
