Agustín de Iturbide y Green (2 April 1863 – 3 March 1925) was the grandson of Agustín de Iturbide, the first emperor of independent Mexico, and his consort Ana María Huarte.
He became the adopted son with the title of Prince of Iturbide, along with his cousin Salvador de Itúrbide y de Marzán, of Mexico's only other royal heads of state—Emperor Maximilian I of Mexico and Empress Carlota of Mexico.
After the death of Emperor Maximilian in 1867, he became the Head of the Imperial House of Mexico, but he had no children.
His claims passed to Maria Josepha Sophia de Iturbide, the daughter of his cousin, Salvador.
