Saigon is a 1948 American crime film directed by Leslie Fenton starring Alan Ladd and Veronica Lake, in their fourth and final film together. It was distributed by Paramount Pictures and was one of the last films Veronica Lake made under her contract with the studio. Ladd and Lake made four films together; This Gun for Hire and The Glass Key, both in 1942, The Blue Dahlia in 1946 and Saigon. While the earlier films all proved to be big box office successes, Saigon did not do as well financially. Ladd continued to remain one of Paramount's top male stars, while Lake's career was in decline. By the end of 1948 her contract with Paramount had expired and the studio chose not to renew it.

For Ladd, Saigon was one of a series of adventure films set in foreign locales, starting with Two Years Before the Mast (1946) and Calcutta (1947).
