João Tamagnini de Sousa Barbosa (December 30, 1883 – December 15, 1948), commonnly known by João Tamagnini Barbosa (pron. IPA2|ʒu'ɐ̃ũ tama'ɲini bɐɾ'bɔzɐ) or just Tamagnini Barbosa was a Portuguese military officer and politician of the Portuguese First Republic (1910-1926). He served as Minister of Interior, Colonies and Finances during the period known as "New Republic", after the coup d'état of the National Republican Party ("Sidonist Party") and the semi-dictatorial government of President/Prime Minister Sidónio Pais, followed by a brief participation in the provisional government of João do Canto e Castro after the assassination of Sidónio Pais.
