Isabella of Parma (Isabella Maria Luisa Antonietta Ferdinanda Giuseppina Saveria Domenica Giovanna; 31 December 1741 – 27 November 1763) was the daughter of Infante Felipe of Spain, Duke of Parma, and his wife, Louise Élisabeth, eldest daughter of Louis XV of France and Maria Leszczynska.
At 18, Isabella was married to Archduke Joseph of Austria, later Joseph II, with whom she was not happy, finding more fulfilment in her close friendship with his sister Archduchess Maria Christina.
The difficult birth of her daughter Maria Theresa, followed by two miscarriages, affected her mental condition, and she died soon after giving birth to another stillborn daughter.
