Gheorghe Tattarescu (Romanian pronunciation: [ˈɡe̯orɡe tataˈresku]; October 1818 - October 24, 1894) was a Moldavian-born Romanian painter and a pioneer of neoclassicism in his country's modern painting.

Tattarescu was born in Focşani in 1818. He started out as an apprentice to his uncle Nicolae Teodorescu, a church painter. He went on to study at the Painting School from Buzău, when Teodorescu moved there. The Orthodox Bishop of Buzău, Chesarie, helped him obtain a scholarship in Rome, where he was taught by professors from the Accademia di San Luca. While there, Tattarescu made copies paintings by Raphael, Bartolomé Estéban Murillo, Salvatore Rosa, and Guido Reni.

Tattarascu was a participant in the 1848 Revolution in Wallachia. After the revolution, he painted portraits of Romanian revolutionaries in exile such as Gheorghe Magheru, Ştefan Golescu, and, in 1851, that of Nicolae Bălcescu (in three almost identical versions). Romantic nationalist ideals were the inspiration for his allegorical compositions with revolutionary (Romania's rebirth, 1849) and patriotic (The Principalities' Unification, 1857 and February 11 - The Modern Romania, 1866) themes.

Gheorghe I. Tătărescu (also known as Guţă Tătărescu, with a slightly antiquated pet form of his given name; 2 November 1886 – 28 March 1957) was a Romanian politician who served twice as Prime Minister of Romania (1934–1937; 1939–1940), three times as Minister of Foreign Affairs (interim in 1934 and 1938; appointed to the office in 1945-1947), and once as Minister of War (1934). Representing the "young liberals" faction inside the National Liberal Party (PNL), Tătărescu began his political career as a collaborator of Ion G. Duca, becoming noted for his anti-Communism and, in time, for his conflicts with the PNL's leader Dinu Brătianu and the Foreign Minister Nicolae Titulescu. During his first time in office, he moved closer to King Carol II, leading an ambivalent policy toward the fascist Iron Guard and ultimately becoming instrumental in establishing the authoritarian and corporatist regime around the National Renaissance Front. In 1940, he accepted the cession of Bessarabia and Northern Bukovina to the Soviet Union, and consequently had to resign.
