Martín de Ursúa

Martín de Ursúa y Arizmendi (; February 22, 1653 – February 4, 1715), Count of Lizárraga and of Castillo, was a Spanish conquistador in Central America during the late colonial period of New Spain. Born in Olóriz, Navarre, he is noted for leading the 1696–97 expeditionary force which resulted in the fall of the last significant independent Maya stronghold, Nojpetén, located on an island in Lake Petén Itzá in the northern Petén Basin region of present-day Guatemala. He served as governor of the Yucatán until 1708, when he was named Governor-General of the Philippines.

In 1692 he was appointed to be governor of Yucatán, with his term to begin in 1698. By 1694 he had been appointed as alcalde ordinario (a Spanish colonial official) of Mexico City.
