The .375 Weatherby Magnum was an American rifle cartridge.

Designed in 1944-45 by Roy Weatherby, the .375 WM was a blown-out, improved round based on the .375 H&H. While similar to the wildcat .375 Ackley Improved Magnum, it was factory available. It is more potent than strictly necessary for North American big game, and is suitable for safari in Africa, except possibly elephant. [Barnes, Frank C., ed. by John T. Amber. "Cartridges of the World" (Northfield, IL: DBI Books, 1972), p.52.] The trajectory with the 270 grain factory load (with a midrange trajectory of 1.9 inches at 200 yards {4.8 cm at 180 m}) approximates the .30-06 [Barnes, p.57.] and is fine for long ranges in North America.

The .375 Weatherby was only ever offered in Weatherby rifles, and was re-introduced in 2001. It is still commercially available, and can be handloaded to approximate factory ballistics, [Barnes, p.57.] or with a lighter 235 grain slug. [Barnes, p.57.] A .375 H&H cartridge can be used in a .375 Weatherby rifle, with a small loss of performance. [Hornady, .375 Weatherby.]
