Reşat Nuri Güntekin (25 November 1889 – 7 December 1956) was a Turkish novelist, storywriter, and playwright. Born in Istanbul, he was a prominent figure in the Turkish literary world, best known for his novel Çalıkuşu ("The Wren", 1922), which explores the fate of a young Turkish female teacher in Anatolia. His other significant works include Dudaktan Kalbe ("From the Lips to the Heart", 1925), and Yaprak Dökümü ("The Fall of Leaves", 1930), among others. Güntekin's narratives are celebrated for their detailed, precise style and realistic tone, making a significant impact on Turkish literature.

Güntekin's father was a major in the army, which provided him a unique perspective on Turkish society. He attended primary school in Çanakkale, Çanakkale Secondary School, and the İzmir School of Freres, before graduating from Istanbul University, Faculty of Literature in 1912. His career spanned various roles, including that of a teacher and administrative positions, which allowed him to closely observe Anatolian people and their social conditions. This deep understanding of the human-environment relationship is reflected in his works, which often deal with life and social problems in Anatolia.

Many of Güntekin's novels have been adapted into cinema and television, demonstrating the widespread appeal and enduring legacy of his stories in Turkish culture. His work Çalıkuşu was notably adapted into a film in 1966 and a TV series in 1986, bringing his insightful observations of Turkish society to a broader audience.
