Don Salvador de Iturbide y Marzán, Prince of Iturbide (18 September 1849, Mexico City - 26 February 1895, Ajaccio, Corsica) was the grandson of Agustín de Iturbide, the first emperor of independent Mexico, and his consort Empress Ana María. He became the adopted son, along with his cousin Agustín de Iturbide y Green, of Mexico's only other royal heads of state—Emperor Maximilian I and Empress Carlota of Mexico.

Salvador de Iturbide y Marzán, born into the Mexican nobility, was the son of Emperor Agustin I's third son Prince Salvador of Mexico and Rosario de Marzán y Guisasola.

When Maximilian and Carlota ascended the throne of Mexico in 1863 with the support of the French troops of Napoleon III, the new monarchs invited the Iturbide family back to Mexico. As it became clear that Maximilian and Carlota could have no children together, they offered to adopt Salvador along with his cousin, Agustín de Iturbide y Green. They formally adopted the cousins on 13 September 1865, granting them the title Prince de Iturbide with the style of "His Highness".

His adoptive mother, Empress Carlota of Mexico sent him to France, where he lived at Paris until 1867, when he moved to Hungary. After seeking the right to a pension as an heir to the Mexican throne, he was awarded one by the Emperor Franz Joseph, Emperor Maximilian's brother; Don Salvador regularly petitioned to have it increased.
