Luís da Silva Mouzinho de Albuquerque (June 16, 1792 in Lisbon – December 27, 1846 in Torres Vedras; ) was a Portuguese military officer, engineer, poet, scientist and politician, who distinguished himself during the Liberal Wars and in the conflicts that marked Portugal's history in the first half of the 19th century. He served as the Minister of the Kingdom (a post similar to today's Minister of Internal Affairs) during the liberal regency of Pedro of Braganza (formerly Pedro I of Brazil and IV of Portugal). This was the most prominent post inside the government at that time, which made him the Prime Minister of Portugal in all but name. He was also several times minister and deputy minister during the Constitutional Monarchical period. Among other offices, he served as Chief of the National Mint, captain-general and governor of Madeira, and inspector-general of public works. He was the grandfather of Joaquim Augusto Mouzinho de Albuquerque, a military officer and colonial administrator.
