Louis Dearborn L'Amour was an American novelist and short story writer. His books consisted primarily of Western novels, though he called his work "frontier stories". His most widely known Western fiction works include Last of the Breed, Hondo, Shalako, and the Sackett series. L'Amour also wrote historical fiction, science fiction, non-fiction (Frontier), and poetry and short-story collections. Many of his stories were made into films. His books remain popular and most have gone through multiple printings. At the time of his death, almost all of his 105 existing works were still in print, and he was "one of the world's most popular writers".

Western fiction is a genre of literature set in the American Old West frontier and typically set from the late eighteenth to the late nineteenth century. Well-known writers of Western fiction include Zane Grey from the early 20th century and Louis L'Amour from the mid-20th century. The genre peaked around the early 1960s, largely due to the popularity of televised Westerns such as Bonanza. Readership began to drop off in the mid- to late 1970s and reached a new low in the 2000s. Most bookstores, outside a few west American states, only carry a small number of Western fiction books.
