Pedro Menendez Márquez (? -?), Marqués de Avilés, was an explorer, Spanish conquistador and governor of Florida. He was a nephew of Pedro Menéndez de Avilés.
Pedro Menéndez Marqués was born probably in Asturias, Spain. He was the son of Marquis Alonso "El Mozo" and of Maria Alonso Arango "La Moza. He had four brothers: Alonso, Juan, Catalina and Elvira Menéndez Marqués. They were nephews of Pedro Menéndez de Avilés. In 1565, along with his uncle, Pedro Menéndez de Avilés and Bartolomé Menéndez, Pedro Alonso and Juan Menendez Marques led the conquest of Florida. They played the command of the troops. The last two were killed in clashes with the Indigenous peoples. On April 3, 1571, Menéndez Marquéz was governor of Cuba and in 1577 he was appointed governor of Florida. In October of that year, he sent to Santa Elena, a military force commanded by who was appointed Governor of Santa Elena to replace Hernando de Miranda. Menéndez Marques anticipated that the Indians might attack any force that tried to return to Santa Elena, so he and Miranda took from St. Augustine a strong prefabricated. He and his 53 men were able to erect it in just six days.
