Zbigniew Pełczyński (Polish pronunciation: [ˈzbʲigɲɛf pɛwˈʈ͡ʂɨj̃skʲi], 29 December 1925 – 22 June 2021) was a Polish-British political philosopher and academic.

Pełczyński was instrumental in providing opportunities for scholars from Poland and other post-communist countries to study at British universities, especially at Oxford and Cambridge.

After 1956, Pełczyński made regular visits to Poland and was instrumental in developing several programmes for the education of students from communist Europe at Oxford.

In the United States, Pełczyński became well known for having been the politics tutor at Oxford University for the Rhodes Scholar and future President Bill Clinton.

The organization, which subsequently changed its name to the School for Leaders Society, states as one of its goals "creating social capital based on leadership".
