Nicolae Fleva (Romanian pronunciation: [nikoˈla.e ˈfleva]; also known as Nicu Fleva, Francized Nicolas Fléva; 1840 – August 4, 1920) was a Wallachian, later Romanian politician, political journalist and lawyer. Known especially for his involvement in political incidents, and for a stated patriotism bordering on demagogy, he tested all political formulas that Romania's two-party system would allow. His activity in the public sphere brought a decades-long presence in the Assembly of Deputies and a mandate as Mayor of Bucharest between 1884 and 1886.
