John Donald McPartland (1911–1958) was a writer specializing in pulp fiction crime whose career was ended by an early death at age 47. In addition to his pulp work, he is known for his more standard novel, No Down Payment, which was later made into the movie of the same title, directed by Martin Ritt and starring Joanne Woodward and Tony Randall, among others.
McPartland also is known for a strongly anti-communist Life magazine article, titled "Portrait of an American Communist," which he penned as a Life magazine staff writer in January 1948.
