Juan Martín de Pueyrredón y O'Dogan (December 18, 1776 - March 13, 1850) was an Argentine general and politician of the early 19th century.

He was born in Buenos Aires, where he was educated at the royal college, which he left in 1791 to assume the responsibilities for the family business after his father's death. In 1795, he went to Cadiz, Spain, and spent the following years travelling through Spain and France.

When the British occupied Buenos Aires in 1806, Pueyrredón fled to the countryside and rallied a volunteer force which eventually recaptured the city. In 1807 he was sent as representative of Buenos Aires to Spain again, but returned in 1809 via Brazil to Buenos Aires, where he subsequently participated in the independentist movement. After the May revolution of 1810, he was appointed governor of Córdoba, and in 1812 he became the leader of the independent forces and a member of the short-lived first triumvirate. Form 1812 to 1815, he was exiled in San Luis. In 1816, he was elected Supreme Director of the United Provinces of La Plata. He stongly supported José de San Martín's military campaign in Chile, but also founded the first national bank of Argentina and the mint. After the declaration of a unitarian constitution, revolts forced him to resign in 1819, and he was exiled to Montevideo.

Subsequently, he no longer played an influential role in politics, although he was involved in some negotiations with Juan Manuel de Rosas in 1828. From 1835 to 1849, he went to Europe with his family. He died in retirement on his ranch near Buenos Aires.
