Ramon Gil de Cuadra (1775 - 1860) was a Spanish scientist and politician active in the early 19th century. Gil de Cuadra traveled extensively throughout the world including documented voyages to North America, South America, the Philippines and British India. He was part of the Spanish embassy to the United States to define the limits to Spanish possessions in the New World. Later, Cuadra is known to have lived for a time in England before returning to Spain in 1836 to accept a commission as the minister of the Interior-Portfolio Direccion Hidrografico. He also served as a Royally appointed Senator-for-life, Director of the Navy, and Minister of the Interior of the Peninsula.
