Doctor Miguel Núñez de Sanabria (1645 or 1646 – 1729) was a Spanish official in Peru and an oidor (judge) of the Audiencia of Lima.
Núñez de Sanabria was born in Lima.
He was a knight of the Order of Santiago and a professor of laws at the University of San Marcos, Lima.
As president of the Audiencia at the time of the death of Viceroy Melchor Portocarrero, 3rd Count of Monclova on September 15, 1705, Núñez de Sanabria took over the government of the colony on an interim basis, until Manuel de Oms y de Santa Pau succeeded him in May 1707.
He served as interim viceroy again, briefly, from April to September 1710.
