George Papandreou, Greek sociologist and politician, 182nd Prime Minister of Greece
George Andreas Papandreou (Greek: Γεώργιος Ανδρέας Παπανδρέου, pronounced [ʝeˈorʝios papanˈðreu], shortened to Giorgos (Γιώργος) [ˈʝorɣos] to distinguish him from his grandfather; born 16 June 1952) is an American-born Greek politician who served as Prime Minister of Greece from 2009 to 2011. He is currently serving as an MP for Movement for Change.

Belonging to a political dynasty of long standing, he served under his father, then-prime minister Andreas Papandreou as Minister for National Education and Religious Affairs (1988–1989 and 1994–1996) and Minister for Foreign Affairs from 1999 to 2004. Papandreou was leader of the Panhellenic Socialist Movement (PASOK) party, which his father founded, from February 2004 until March 2012, and has been President of the Socialist International since January 2006.

On 6 October 2009, George Papandreou became the 182nd Prime Minister of Greece. He was the third member of the Papandreou family to serve as the country's prime minister, following his father Andreas and his grandfather Georgios Papandreou. He resigned on 11 November 2011 during the Greek government debt crisis to make way for a national unity government.

In March 2012, he resigned as leader of PASOK, and in January 2015, he left the party completely, founding his own political party, the Movement of Democratic Socialists (KIDISO), which was the 8th most voted-for party in the January 2015 elections, but did not manage to enter Parliament. In 2017, KIDISO joined the Democratic Alignment, a political alliance formed by PASOK and other centre-left parties. Democratic Alignment later evolved into Movement for Change, which in the 2019 elections was the third most voted-for party, with Papandreou himself returning to Parliament as an MP representing the region of Achaea.
