Berthe de Rohan (French: Marie-Berthe Françoise Félicie Jeanne de Rohan, Princesse de Rohan; 21 May 1868 – 19 January 1945) was a Princess of Rohan and member of the House of Rohan by birth. She was born in Teplitz, Kingdom of Bohemia, Austria-Hungary. Through her marriage to Carlist claimant to the Spanish throne, Berthe became a member of the House of Bourbon and titular Queen consort of Spain, France, and Navarre.

Marie-Berthe Françoise Félicie Jeanne was the ninth and youngest child of Prince Arthur of Rohan (1826-1885) (son of Prince Benjamin de Rohan-Rochefort-Guéménée and Princess Stephanie of Croÿ) and his wife, Countess Maria Gabriela of Waldstein-Wartenberg (1827-1890) (daughter of Count Christian Vinzenz Ernst von Waldstein-Wartenberg and Countess Maria Franziska of Thun und Hohenstein).^[1]

Berthe married Carlos de Bourbon, Duke of Madrid, second son, eldest son of Juan de Bourbon, Count of Montizón and his wife Archduchess Maria Beatrix of Austria-Este, on 28 April 1894 in Prague.

After the death of his first wife Princess Margherita of Bourbon-Parma, their union was encouraged by his mother Archduchess Maria Beatrix of Austria-Este (1824–1906), but produced no issue.

Berthe died in relative obscurity in Vienna, Greater German Reich, at the age of 76. She was buried in Klosterkirche, Döbling, Austria.^[2]
