The Ex-Mrs. Bradford is a 1936 American comedy mystery film. William Powell and Jean Arthur star as a divorced couple who investigate a murder at a racetrack. This was the last film directed by Stephen Roberts before his death from a heart attack.

The similarity between RKO's The Ex-Mrs. Bradford and M-G-M's The Thin Man (1934) was speculated about given the chances that RKO's film would eclipse After the Thin Man (1936), which was to be released later in the year, at the box office. Modern sources claim that the film was RKO's third most successful production of 1936.
