Martín Cortés el Mestizo (; c. 1523 – c. 1595) was the first-born and illegitimate son of  Hernán Cortés and Doña Marina, the conquistador’s interpreter and concubine. He is considered to be one of the first mestizos of New Spain and is known as “El Mestizo.” His exact date of birth is not precisely known. Until the birth of Martín's younger brother, don Martín Cortés Zúniga, to his father and his aristocratic second wife, Martín, son of La Malinche, was Cortés's only male heir, despite his illegitimate birth. Cortés's first marriage to Catalina Suárez was childless. He grew up in Spain but returned to the new world as a young man. As heirs of Cortés he and his brother were considered a threat to the vice regal rule, and they were accused of participating in a plot to overthrow the viceroy. He was arrested and tortured and exiled to Spain where he died.
