William Peter McGivern was an American novelist and television scriptwriter. He published more than 20 novels, mostly mysteries and crime thrillers, some under the pseudonym Bill Peters.

Odds Against Tomorrow is a 1959 American film noir produced and directed by Robert Wise and starring Harry Belafonte, Robert Ryan and Ed Begley. Belafonte selected Abraham Polonsky to write the script, which is based on a novel of the same name by William P. McGivern. Blacklisted in those years, Polonsky had to use a front and John O. Killens was credited. Polonsky's screenwriting credit was restored in 1996 in his own name.
