The .40-65 Winchester (also called the .40-65 Winchester and Marlin) [Barnes, Frank C., ed. by John T. Amber. "Cartridges of the World" (Northfield, IL: DBI Books, 1972), p.94, ".40-65 Winchester".] was an American rifle cartridge.

Introduced with the 1887 Winchester Model 86, and available in Winchester single shots and in the Marlin Model 95, it was "a further effort to put more steam" in repeating rifle cartridges. [Barnes, and Amber, p.94.]

It was commercially available in black and smokeless varieties until around 1935, and can be handloaded by fire-forming .45-70 brass. [Barnes, and Amber, p.94.]
