The Nobel Prize in Literature is a Swedish literature prize that is awarded annually, since 1901, to an author from any country who has, in the words of the will of Swedish industrialist Alfred Nobel, "in the field of literature, produced the most outstanding work in an idealistic direction". Though individual works are sometimes cited as being particularly noteworthy, the award is based on an author's body of work as a whole. The Swedish Academy decides who, if anyone, will receive the prize. The academy announces the name of the laureate in early October. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895. Literature is traditionally the final award presented at the Nobel Prize ceremony. On some occasions, the award has been postponed to the following year, most recently in 2018.

Pär Fabian Lagerkvist was a Swedish author who received the 1951 Nobel Prize in Literature.
