The Colt Diamondback is a revolver manufactured by Colt's Manufacturing Company of Hartford, Connecticut, in calibers of .22 LR, .22 WMR and .38 Special. Inspired by the successful Colt Python, the Diamondback was manufactured from 1966 to 1988 and was available in barrel lengths of 2½, 4, and 6 inches.

Colt introduced the double-action Diamondback as a deluxe model in 1966. It has a wide serrated target hammer, ventilated rib, fully adjustable target quality sights, and full-length barrel underlug. It is a 6-shot revolver with a swing-out cylinder and was available in blue or nickel finishes. Visually, the Diamondback resembles a scaled-down version of the Python. It was dropped from production in 1988

Because of the light recoil of .22 caliber ammunition, the .22 version of the Diamondback can be used as a training gun for novice shooters. It had gained popularity with gun enthusiasts due to the inexpensive price of .22 caliber ammunition and since it has been discontinued, for its rarity.

In addition, the Diamondback was marketed to law enforcement agencies who did not allow the use of the .357 Magnum cartridge.
