Antonio María Martínez (died 1823) was a colonel in the infantry regiment of Zamora and the last governor of Spanish Texas.
He was born in Andújar, province of Jaén, Spain. He entered military service on July 7, 1785, and had a distinguished career, winning the Cross of Northern Europe and the Cross of Germany on European battlefields. He assumed the political and military governorship of Spanish Texas on March 27, 1817.
By the summer of 1821, the Spanish regime was faced with disaster. Agustín de Iturbide was in possession of Mexico, and Martínez, at the request of the Baron de Bastrop, approved Moses Austin's petition for permission to bring 300 settlers into Texas. On July 18, 1821, Martínez was forced to issue orders requiring the oath of allegiance to Iturbide. After learning that José Félix Trespalacios had been appointed to succeed him, he surrendered his office peacefully on August 17, 1822.
Martínez returned to Mexico City and died there in November 1823.
