The .476 Nitro Express is a British rifle cartridge.

Introduced by Westley Richards around 1907, it follows on the heels of the .470, .475, and .475 No. 2 Nitro Express rounds. While it was available in single and double rifles, it was less popular than other comparable rounds. It is nearly identical in performance to a number of others in the same class.

The .476 is considered adequate for all African and Indian big game, [Barnes, Frank C., ed. by John T. Amber. "Cartridges of the World" (Northfield, IL: DBI Books, 1972), p.229, ".476 Nitro Express".] including elephant and rhino. Its ballistics resemble the .458 Winchester Magnum, with a larger diameter bullet; whether this is an advantage remains in dispute. [Barnes, and Amber, p.229.]

Commercial rifles are no longer available in .476 Nitro Express except by special order, ammunition is no longer commercially available, and handloading data are scant. [Barnes, and Amber, p.229.] The factory load used 75 gr (4.86 g) of cordite over a 520 gr (33.7 g) slug. [Barnes, and Amber, p.229.]
