Random House was founded in 1925 by Americans Bennett Cerf and Donald Klopfer, two years after they acquired the Modern Library imprint from publisher Horace Liveright, which reprints classic works of literature. Cerf is quoted as saying, "We just said we were going to publish a few books on the side at random," which suggested the name Random House. In 1934 they published the first authorized edition of James Joyce's novel Ulysses in the Anglophone world.

Random House entered reference publishing in 1947 with the American College Dictionary, which was followed in 1966 by its first unabridged dictionary.

The publisher's main office in the United States is located at 1745 Broadway in Manhattan, in the 684-foot Random House Tower, completed in 2009 and spanning the entire west side of the block between West 55th Street and West 56th. Its lobby showcases floor-to-ceiling glassed-in bookcases filled with books published by the company's many imprints. Earlier addresses were 457 Madison Avenue, New York 22, NY; 20 East 57th Street, New York 22, NY; and 201 East 50th Street, New York, NY 10022.
