Georgi Pirinski (Bulgarian: Георги Пирински) (born 10 September 1948) is a Bulgarian politician of the Bulgarian Communist Party and after 1990 of the Bulgarian Socialist Party (BSP). Born in New York City, U.S. in the emigrant family of Communist functionary Georgi Pirinski, Sr., he has roots from Pirin Macedonia. His mother Pauline was born in New York City and was a member of the Young Communist League at the City College of New York. She was a professor of English at Sofia University. His father found refuge in the U.S. after he participated in the unsuccessful Communist uprising against the Bulgarian regime in 1923 and was expelled from the U.S. as an undesirable alien about 1951. While a convinced communist, Pirinski did show some flashes of independent thinking, such as expressing disagreement in a private conversation with foreign visitors in 1970 at the decision of Bulgarian media to downplay the U.S. moonwalk the previous year. In the late 1970s, Pirinski was an aide to then Deputy Prime Minister Georgi Lukanov and then at the age of 31 became Bulgaria's youngest deputy minister (of foreign trade). He renounced his U.S. citizenship in 1974, but political opponents later argued that the renunciation was judicially null. Pirinski was considered the BSP's favorite for the 1996 presidential nomination until the Constitutional Court barred him from participating in the presidential elections for failing to satisfy a constitutional requirement that the president be a Bulgarian citizen by birth (he was a U.S. citizen by birth).
A vice-premier during the Georgi Atanasov and Andrey Lukanov governments and a foreign minister during the Zhan Videnov government, Pirinski was the Chairman of the National Assembly of Bulgaria from 11 July 2005 to 25 June 2009.
