Jerzy Nowosielski (January 7, 1923 – February 21, 2011) was a Kraków-born Polish painter, graphic artist, scenographer, and illustrator.
He was well known for his religious compositions (wall paintings, iconostases, polychromies) in the Orthodox Churches in Kraków, Bialystok and Jelenia Góra, the Roman Catholic Church of the Holy Cross at Wesola, the Franciscan Church in the Azory district of Kraków, and the Greek Catholic Church in Lourdes, France.
Nowosielski designed and erected the Church of the Birth of the Blessed Virgin Mary in Bialy Bór.
He also painted portraits, landscapes, still life, and abstract pictures.
His works are found in Polish museums and also in private collections in Canada, the USA, and Germany.
In 1993 he was awarded a prize by the Polish cultural foundation Wielka Fundacja Kultury and received an honorary doctorate from the Jagiellonian University in 2000.
