Arnold Book Company (ABC) was a British publisher of comic books that operated in the late 1940s and 1950s, most actively from 1950 to 1954. ABC published original titles like the war comic Ace Malloy of the Special Squadron and the science fiction title Space Comics, and reprints of American horror and crime titles (many featuring the work of Joe Simon and Jack Kirby) like Adventures into the Unknown, Black Magic Comics, and Justice Traps the Guilty. British contributors to the company's titles include Mick Anglo and Denis Gifford. Arnold Book Company was closely connected to the fellow British comics publisher L. Miller & Son.
