Joaquim Augusto Mouzinho de Albuquerque (Batalha, Quinta da Várzea, November 12, 1855 – Lisbon, January 8, 1902) was a Portuguese soldier. He captured Gungunhana in Chaimite (1895) and pacified Mozambique. He was a grandson of Luís da Silva Mouzinho de Albuquerque.
Highly respected in Portuguese society of the 19th and 20th centuries, he was seen as the hope and symbol of Portuguese reaction to threats against Portuguese interests in Africa from the more powerful northern European empires, such as Great Britain.
He married his cousin Maria José Mascarenhas de Mendonça Gaivão (July 23, 1857 – ?), without issue.
He was governor of Gaza Province and Mozambique until 1898 when he returned to Portugal.
He was the instructor of Crown Prince Luís Filipe.
He allegedly committed suicide in 1902 (some sources claim he was killed).
