Jerzy Andrzejewski (August 19, 1909, Warsaw, Congress Poland, Russian Empire - April 19, 1983, Warsaw) was a prolific Polish author. In 1976 he was one of the founding members of the intellectual opposition group KOR (Workers' Defence Committee). On 23 September 2006, he was posthumously given the rank of Commander of the Order of Polonia Restituta.
Two of his novels, Ashes and Diamonds, about post-war Poland, and Holy Week, dealing with the Warsaw Ghetto Uprising, have been turned into film adaptations by the Oscar-winning Polish director Andrzej Wajda.
Holy Week and Ashes and Diamonds have both been translated into English.
Although he was frequently considered to be a front-runner for the Nobel Prize for Literature, he was never awarded.
Andrzejewski was a strong supporter of Poland's anti-Communist Solidarity movement.
