Pierre Eugène Bérégovoy (French pronunciation: [pjɛʁ beʁeɡɔvwa]; 23 December 1925 – 1 May 1993) was a French Socialist politician. He served as Prime Minister under François Mitterrand from 1992 to 1993.

Pierre Bérégovoy was born in Déville-lès-Rouen, Seine-Maritime to a Ukrainian father (original family name Береговий in Ukrainian or Береговой in Russian) who had left the Russian Empire after the Russian Civil War, and a French mother.

He started his professional life at the age of 16 as a qualified metal worker. He got involved in politics following his activities in the French Resistance – while working at SNCF during World War II. A member of the SFIO Socialist Party and of the trade unions confederation Workers Force, he joined the staff of the Minister of Public Works and Transport, Christian Pineau, as adviser for relations with the trade unons in 1949. One year later, he became technical agent in Gaz de France.

In 1959, he left the SFIO and participated in the foundation of the dissident Unified Socialist Party (PSU). He became an adviser of Pierre Mendès-France. In 1967, with Alain Savary, he created the pro-Mendès-France Union of clubs for the renewal of the left. This group joined the renewed Socialist Party (PS) in 1969. He joined the executive group of the party behind François Mitterrand, and participated notably in the negotiations of the Common Program of the Union of the Left.

François Maurice Adrien Marie Mitterrand (French: [fʁɑ̃swa mɔʁis mitɛˈʁɑ̃] ( listen); 26 October 1916 – 8 January 1996) was the 21st President of the French Republic and ex officio Co-Prince of Andorra, serving from 1981 until 1995. He is the longest-serving President of France and, as leader of the Socialist Party, the first figure from the left elected President under the Fifth Republic.

Reflecting family influences, Mitterrand started political life on the Catholic nationalist right. He served under the Vichy Regime in its earlier years. Subsequently, however, he joined the Resistance, moved to the left, and held ministerial office repeatedly under the Fourth Republic. He opposed de Gaulle's establishment of the Fifth Republic. Although at times a politically isolated figure, Mitterrand outmanoeuvred rivals to become the left's standard bearer in every presidential election from 1965 to 1988, except 1969. Elected President in the May 1981 presidential election, he was re-elected in 1988 and held office until 1995.
