The .22 Winchester Rimfire (commonly called the .22 WRF) is a American rimfire rifle cartridge.

Introduced in the Winchester M1890 slide rifle, it had a flat-nose slug, and is identical to the .22 Remington Special (which differed only in having a roundnosed slug). [Barnes, p.275, ".22 Winchester Rimfire (WRF)".] It uses a flat-based, inside-lubricated bullet, which differs from the outside-lube slug of the .22 Short, Long, LR, and Extra Long rounds. [Barnes, p.275, ".22 Winchester Rimfire (WRF)".]

The .22WRF "was the first notable improvement in the killing power" over the .22LR,. [Barnes, p.275, ".22 Winchester Rimfire (WRF).] and was able to kill cleaner at up to 75 yd (70 m), though it was somewhat less accurate than the .22LR. [Barnes, p.275, ".22 Winchester Rimfire (WRF)".] It is only really suited to small game, such as rabbits or prairie dogs. [Barnes, p.275, ".22 Winchester Rimfire (WRF).]

Available at one time in a variety of Winchester, Remington, and Stevens single-shots and repeaters, it stopped being offered in new rifles, but was still commercially loaded as late as 1972. [Barnes, p.275, ".22 Winchester Rimfire (WRF)".] It can be fired in any rifle chambered for the more powerful .22 WMR. [Barnes, p.275, ".22 Winchester Rimfire (WRF)".]
