William Brown (22 June 1777 – 3 March 1857) was an Irish sailor, merchant, and naval commander who served in the Argentine Navy during the wars of the early 19th century. Brown's successes in the Argentine War of Independence, the Cisplatine War, and the Anglo-French blockade of the Río de la Plata earned the respect and appreciation of the Argentine people, and he is regarded as one of Argentina's national heroes. The creator and first admiral of the country's maritime forces, he is commonly known as the "father of the Argentine Navy".
