Bernardo de Gálvez y Madrid, Viscount of Galveston and Count of Gálvez (Spanish: Bernardo de Gálvez y Madrid, vizconde de Gálveztown y conde de Gálvez) (July 23, 1746, Málaga, Spain—November 30, 1786, Mexico City) was a Spanish military leader and the general of Spanish forces in New Spain who served as governor of Louisiana and Cuba and as viceroy of New Spain.

Gálvez aided the Thirteen Colonies in their quest for independence and led the Spanish armies against Britain in the Revolutionary War, defeating the British at Pensacola and reconquering Florida for Spain. He spent the last two years of his life as viceroy, succeeding his father Matías de Gálvez y Gallardo, who had been viceroy before him. Galveston, Texas and several other places are named for him.

Gálvez was born in Macharaviaya, a mountain village in the province of Málaga, Spain, on July 23, 1746. He studied military sciences at the Academia de Ávila and at the age of 16 participated in the War against Portugal, where he was promoted to lieutenant. He arrived in New Spain, then Mexico, in 1762. As a captain, he fought the Apaches, with his Opata Indian allies. He received many wounds, several of them serious. In 1770, he was promoted to commandant of arms of Nueva Vizcaya y Sonora, northern provinces of New Spain, comprising even New Mexico.

In 1772, he returned to Spain in the company of his uncle, José de Gálvez. Later, he was sent to Pau, France with the Cantabria regiment. There, he learned to speak French, which served him well when he became governor of Louisiana. He was transferred to Seville, in 1775, and then participated in the disastrous expedition of O’Reilly to Algiers. Gálvez himself was seriously wounded. After capturing the fortress that guarded the city, he was promoted to lieutenant colonel. He then became a professor at the military academy of Ávila.

In 1777, he was sent to Louisiana, as a colonel and interim governor of the province. This was the large territory that later became the Louisiana Purchase. It had been ceded by France to Spain, in 1763, in compensation for the loss of Florida to England. In 1779, he was promoted to brigadier.

In 1777, he married doña Marie Felice de Saint-Maxent Estrehan, a young Criolla widow. They had three children, Miguel, Matilde and Guadalupe.

He practiced an anti-British policy as governor, taking measures against British smuggling and promoting trade with France. He also established free trade with Cuba and Yucatán. He founded Galvez Town, in 1778, and promoted colonization of Nueva Iberia.
