Jerzy Kosiński (Polish pronunciation: [ˈjɛʐɨ kɔˈɕij̃skʲi]; born Józef Lewinkopf; June 14, 1933 – May 3, 1991) was a Polish-American writer and two-time president of the American Chapter of P.E.N., who wrote primarily in English.

Born in Poland, he survived World War II in Poland as a Jewish boy and, as a young man, emigrated to the U.S., where he became a citizen. He was known for various novels, among them Being There (1971) and the controversial The Painted Bird (1965), which were adapted as films in 1979 and 2019, respectively.
