Maria Antonia of Parma (Maria Antonia Giuseppa Walburga Anna Luisa Vicenza Margherita Caterina; 28 November 1774 – 20 February 1841) was a Princess of Parma, daughter of Duke Ferdinand I of Parma and his wife, Archduchess Maria Amalia of Austria.
Contrary to what has been frequently stated, she was not named after her aunt, Queen Marie Antoinette of France, who was not her godmother.
Maria Antonia's godparents were her uncle, Emperor Joseph II, and her father's aunt, Maria Antonia of Spain, Queen of Sardinia, after whom the princess was named.
