As of 2025, the Nobel Prize in Literature has been shared by two laureates on four occasions.
Those shared prizes were awarded in 1904, 1917, 1966, and 1974. In 1904, Frédéric Mistral shared the award with José Echegaray y Eizaguirre; in 1917, Karl Adolph Gjellerup shared it with Henrik Pontoppidan. The 1966 prize went jointly to Shmuel Yosef Agnon and Nelly Sachs, while the 1974 prize was shared by Eyvind Johnson and Harry Martinson.
This is a useful distinction from years in which more than one Literature prize was announced. The Swedish Academy did not award a Literature prize in 2018, then announced the 2018 and 2019 laureates together in 2019; those were two separate prizes, not one prize shared by two writers.
By the end of 2025, the Literature prize had been awarded 118 times to 122 laureates. The difference between those totals reflects the four occasions on which one prize was divided between two people. No Literature prize has been shared among three laureates.
