Literature of the 20th century refers to world literature produced during the 20th century (1901 to 2000).

The main periods in question are often grouped by scholars as Modernist literature, Postmodern literature, flowering from roughly 1900 to 1940 and 1960 to 1990Lewis, Barry. "Postmodernism and Literature." The Routledge Companion to Postmodernism NY: Routledge, 2002, p. 121. respectively, roughly using World War II as a transition point. After 1960, the somewhat malleable term "contemporary literature" widely appears.

Although these terms (modern, contemporary and postmodern) are generally applicable to and stem from Western literary history, scholars often use them in reference to Asian, Latin American and African literatures. Non-western writers, in particular in Postcolonial literature, have been at the forefront of literary evolution during the twentieth century.

Technological advances facilitated lower production cost for books, coupled with rising populations and literacy rates, which resulted in a significant rise in production of popular literature and trivial literature, comparable to the similar developments in music. The division of "popular literature" and "high literature" in the 20th century is overlapped by genres such as detectives or science fiction, despite being largely ignored by mainstream literary criticism for most of the century. These genres developed their own establishments and critical awards; these include the Nebula Award (since 1965), the British Fantasy Award (since 1971) or the Mythopoeic Awards (since 1971).

Towards the end of the 20th century, electronic literature grew in importance in light of the development of hypertext and later the World Wide Web.

The Nobel Prize in Literature was awarded annually throughout the century (with the exception of 1914, 1918, 1935 and 1940–1943), the first laureate (1901) being Sully Prudhomme. The New York Times Best Seller list has been published since 1942.

The best-selling literary works of the 20th century are estimated to be The Lord of the Rings (1954/55, 150 million copies), Le Petit Prince (The Little Prince, 1943, 140 million copies), Harry Potter and the Philosopher's Stone (1997, 120 million copies) and And Then There Were None (1939, 115 million copies). The Lord of the Rings was also voted "book of the century" in various surveys. Perry Rhodan (1961 to present) proclaimed as the best-selling book series, with an estimated total of 1 billion copies sold.

1901–1918

The Fin de siècle movement of the Belle Époque persisted into the 20th century, but was brutally cut short with the outbreak of World War I (an effect depicted e.g. in Thomas Mann's The Magic Mountain, published 1924). The Dada movement of 1916–1920 was at least in part a protest against the bourgeois nationalist and colonialist interests which many Dadaists believed were the root cause of the war; the movement heralded the Surrealism movement of the 1920s.

Interwar period

The 1920s were a period of literary creativity, and works of several notable authors appeared during the period. D. H. Lawrence's novel Lady Chatterley's Lover was a scandal at the time because of its explicit descriptions of sex. James Joyce's novel, Ulysses, published in 1922 in Paris, was one of the most important achievements of literary modernism.
