Diego de Gardoqui, the fourth of eight children, was the financial intermediary between the Spanish Court and the Colonies during the American Revolutionary War, meeting with John Jay on various occasions. He was a Basque and a member of the wealthy Gardoqui family of Bilbao, Spain. The mercantile business of "José de Gardoqui e Hijos" in Bilbao (of which Diego was one of three sons in a partnership with their father) supplied the patriots with war supplies during the war.
In November 1775, Gardoqui supplied the Massachusetts troops with 300 muskets with bayonets. The trading firm Joseph Gardoqui and Sons supplied Spanish blankets, tents, boots, and uniforms that helped keep hundreds of Continental Army soldiers warm through the brutal winter of 1777 at Valley Forge.
After the Revolution he became Spain's first envoy to the United States. He arrived in New York in the Spring of 1785.

Gardoqui, as a Spanish diplomat, operated under the ministry of José Moñino, 1st Count of Floridablanca. He became Finance Minister in 1791, when Minister Pedro López de Lerena, Count of Lerena, suffered a debilitating illness. Gardoqui was officially named Finance Minister after the death of Count de Lerena, in 1792.
Gardoqui was the Spanish counterparty to the Jay–Gardoqui Treaty of 1789, negotiated by John Jay of the United States, relating to the navigational rights of Spain in the Mississippi River. Gardoqui, in 1785–86, had arranged for a Spanish horse to be sent to Jay.
In 1785, Gardoqui laid the cornerstone of the first Catholic Church in New York City, St. Peter's on Barclay Street.
After Gardoqui returned to Spain in 1788, he was later succeeded in the United States by two diplomats, José de Jaudenes y Nebot and José Ignacio de Viar (serving as chargés d'affaires to the U.S.), both of whom had served on Gardoqui's own staff during his 1785–1788 tenure.
Gardoqui was elected to the American Philosophical Society in 1789.
