The 1903 Nobel Prize in Literature was the third prestigious literary prize based upon Alfred Nobel's will, which awarded to the Norwegian poet and politician Bjørnstjerne Bjørnson (1832–1910) "as a tribute to his noble, magnificent and versatile poetry, which has always been distinguished by both the freshness of its inspiration and the rare purity of its spirit." The prize was announced in October 08, 1903 and was given in December 10, 1903 at Stockholm.

Bjørnstjerne Martinius Bjørnson was a Norwegian writer who received the 1903 Nobel Prize in Literature "as a tribute to his noble, magnificent and versatile poetry, which has always been distinguished by both the freshness of its inspiration and the rare purity of its spirit". The first Norwegian Nobel laureate, he was a prolific polemicist and extremely influential in Norwegian public life and Scandinavian cultural debate. Bjørnson is considered to be one of the four great Norwegian writers, alongside Ibsen, Lie, and Kielland. He is also celebrated for his lyrics to the Norwegian national anthem, "Ja, vi elsker dette landet". The composer Fredrikke Waaler based a composition for voice and piano on a text by Bjørnson, as did Anna Teichmüller.
