Diego José Pedro Víctor Portales y Palazuelos (; June 16, 1793 – June 6, 1837) was a Chilean statesman and entrepreneur. As a minister of president José Joaquín Prieto's government, he played a pivotal role in shaping the state and politics in the 19th century, delivering with the Constitution of 1833 the framework of the Chilean state for almost a century. Portales' influential political policies included unitarianism, presidentialism and conservatism which led to the consolidation of Chile as a constitutional, authoritarian republic with the franchise restricted to upper class men.

On August 15, 1819 he married his cousin, Josefa Portales y Larraín. He had two daughters with her, both of whom died within days of their birth. His wife also died soon after in 1821. He never remarried, but took Constanza Nordenflicht as his mistress, with whom he had three children. In July 1821, he resigned from his job at the Mint and went into business. He opened a trading house, Portales, Cea and Co., based in Valparaiso with a branch in Lima, Peru. He bid and obtained management of the government monopoly on tobacco, tea, and liquor (known in Spanish as estanco). In exchange for the monopoly, he offered to service in full Chile's foreign debt.
