Vintilă Ion Constantin Brătianu (16 September 1867 – 22 December 1930) was a Romanian politician who served as Prime Minister of Romania between 24 November 1927 and 9 November 1928. He and his brothers Ion I. C. Brătianu and Dinu Brătianu were the leaders of the National Liberal Party of Romania, founded by their father, Ion C. Brătianu.

Born at his family's estate of Florica, in Ștefănești, Argeș County, Vintilă Brătianu started his studies at Saint Sava High School in Bucharest. He then went to France to study engineering at École Centrale Paris from 1886 to 1890. After returning to Romania, he entered politics.

From 1907 to 1911 he was Mayor of Bucharest.^[1] During World War I, he was Minister of War (15 August 1916–19 July 1917) and then Minister for War Munitions.

In November 1927 he also assumed the presidency of the National Liberal Party; he remained in that position until the end of his life.

On 22 December 1930 Brătianu was at his estate in Mihăești, Vâlcea, when he had a stroke of apoplexy which paralyzed his left side; he died that evening at the hospital in nearby Râmnicu Vâlcea.^[3] He is buried at the family estate, Florica, in a crypt where also lie his father Ion C.
