The Two-Gun Kid is the name of two Western fictional characters appearing in American comic books published by Marvel Comics. The first, Clay Harder, was introduced in a 1948 comic from Marvel predecessor Timely Comics. The second, Matt Hawk a.k.a. Matthew J. Hawkins, was introduced in 1962 and has continued to appear into the 2010s. The latter Kid is better known, thanks primarily to his connection with, and later full integration into, the shared continuity of Marvel Comics known as the Marvel Universe, but the Clay Harder Kid enjoyed a 14-year span in comics.

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.
