The Ruger No. 1 is a single-shot rifle introduced and manufactured by Sturm, Ruger & Co. since 1967. it is designed with a Farquharson-style hammerless falling-block action, where an underlever lowers the breechblock to expose the chamber and allow cartridge loading, and closing the lever sets the rifle in battery and also cocks the hammer. A shotgun-style tang safety secures the hammer and sear.

The Ruger No. 1 is available with an Alexander Henry, Beavertail or Mannlicher-style forearm. The rifles came in several sub-models: 1A, 1AB, 1B, 1H, 1S, 1V and RSI(K designation refers to Stainless with laminated stocks). The No. 1 also comes with barrel lengths ranging from 20 to 28 in (510 to 710 mm) and in a multitude of calibers. Lenard Brownell, commenting on his work at Ruger, said of the No. 1: "There was never any question about the strength of the action. I remember, in testing it, how much trouble I had trying to tear it up. In fact, I never did manage to blow one apart."
