Leszek Henryk Balcerowicz (pronounced [ˈlɛʂɛk balt͡sɛˈrɔvit͡ʂ]; born 19 January 1947) is a Polish economist, statesman, and Professor at Warsaw School of Economics. He served as Chairman of the National Bank of Poland (2001–2007) and twice as Deputy Prime Minister of Poland (1989–1991, 1997–2001).

In 1989, he became Minister of Finance in Tadeusz Mazowiecki's first non-communist government and led the free-market economic reforms, proponents of which say they have transformed Poland into one of Europe's fastest growing economies, but which critics say were followed by a large increase in unemployment. In 2007, he founded the Civic Development Forum (Forum Obywatelskiego Rozwoju) think-tank and became the chairman of its council.
