On 26 June 1797 in Foggia, Maria Clementina married the Duke of Calabria, eldest surviving son of Ferdinand IV of Naples and, Maria Carolina of Austria. Prince Francis was the Heir apparent to both the Neapolitan and Sicilian throne's. This marriage was the last of three between the Austrian and Neapolitan royal families, the previous two being between Archduke Francis, her oldest brother and Maria Teresa of Naples and Sicily in 1790 after Archduke Ferdinand and Luisa of Naples and Sicily. They were double first cousins as they shared all their grandparents in common. They had two children. She died in Naples after giving birth to a son the previous year which undermined her health. She is thought to have died from lung disease or tuberculosis. She was buried in Basilica of Santa Chiara, Naples with her son. 
After her death, her husband married Infanta Maria Isabella of Spain, again his first cousin, the youngest surviving daughter of Charles IV of Spain (brother of Maria Clementina's mother) and Maria Luisa of Parma. 
Her only daughter Carolina, married Charles Ferdinand, Duke of Berry in April 1816. He was the son of Charles X of France and Maria Teresa of Savoy. They were the parents of the French pretender Henri d'Artois, Count of Chambord and the Duchess of Parma making Maria Clementina an ancestress of the present Duke of Calabria and his rival the Duke of Castro.
