Martin M. Goldsmith (November 6, 1913 – May 24, 1994) was an American screenwriter and novelist who wrote several classic B-movies including Detour (1945), which he adapted from his 1939 novel of the same name; Blind Spot (1947); and The Narrow Margin (1952), for which he earned an Academy Award nomination.

Goldsmith, at one time the brother-in-law of actor Anthony Quinn, also contributed some stories to The Twilight Zone in 1964.
