Jacinto de Romarate Salamanca (1775 – 1836) was a Spanish Navy officer who fought in the British invasions of the River Plate and on the Royalist side during the Argentine War of Independence.
He participated in the recaptured of Buenos Aires during the first British invasion of the River Plate, commanding the ship La Vizcaína.
Romarate did not accept the legitimacy of the government Junta established in 1808 by Javier de Elío in Montevideo, and moved to Buenos Aires.
Montevideo declared war on Buenos Aires, and Romarate fought in the naval blockade imposed to the city.
During the battle of San Nicolás, he defeated a rudimentary flotilla, which was sending reinforcements to Manuel Belgrano in the Paraguay campaign.
