Bruno Kreisky (German: [ˈbʁuːno ˈkʁaɪ̯ski]; 22 January 1911 – 29 July 1990) was an Austrian social democratic politician who served as Foreign Minister from 1959 to 1966 and as Chancellor from 1970 to 1983. Aged 72 at the end of his chancellorship, he was the oldest Chancellor after World War II. His 13-year tenure was the longest of any Chancellor in republican Austria.

With his 13-year chancellorship, known as the Kreisky era, he is one of the most important political figures in the country as well as in Western European social democracy. Partly at the same time as him, the Social Democrats Willy Brandt of West Germany and Olof Palme of Sweden were heads of government, with whom he worked closely in the Socialist International.
