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 American television to show a single parent raising a child.

The program was titled to reflect McCain's use of a Winchester Model 1892 rifle (an anachronism, as the show was set in the 1880s) which had been customized to allow repeated firing by cycling its lever action. He demonstrated this technique in the opening credits, as well as a second modification that allowed him to cycle the action with one hand using a technique known as "spin-cocking".
