"Casino Royale" is a live 1954 television adaptation of the 1953 novel of the same name by Ian Fleming. An episode of the American dramatic anthology series Climax!, the show was the first screen adaptation of a James Bond novel, and stars Barry Nelson, Peter Lorre, and Linda Christian. Though he is based on the literary Bond, Nelson's character is played as an American spy working for the "Combined Intelligence Agency".

Most of the largely forgotten show was uncovered by film historian Jim Schoenberger in 1981, with the ending (including credits) found later. Both copies are black and white kinescopes, but the original live broadcast was in colour. The episode has since lapsed into the public domain in the United States and countries that apply the rule of the shorter term due to not having its copyright renewed.
