The Rifleman is an American Western television series starring Chuck Connors as rancher Lucas McCain and Johnny Crawford as his son Mark McCain. It was set in the 1880s in the fictional town of North Fork, New Mexico Territory. The show was filmed in black and white, in half-hour episodes. The Rifleman aired on ABC from September 30, 1958, to April 8, 1963, as a production of Four Star Television. It was one of the first primetime series on US television to show a single parent raising a child.

Television Westerns are programs with settings in the later half of the 19th century in the American Old West, Western Canada and Mexico during the period from about 1860 to the end of the so-called "Indian Wars". More recent entries in the Western genre have used the neo-Western subgenre, placing events in the modern day, or the space Western subgenre but still draw inspiration from the outlaw attitudes prevalent in traditional Western productions.
