Shadows Over Chinatown is a 1946 American mystery film directed by Terry O. Morse and starring Sidney Toler, Victor Sen Yung and Tanis Chandler.

He is assisted officially by detective Jeff Hay and police captain Allen, and unofficially by his Number Two Son Jimmy and chauffeur Birmingham Brown.

Sidney Toler had been diagnosed with terminal cancer, but insisted on continuing his commitment to the film series.

Although Toler remains the central actor, some of the action is diverted to Jimmy (Victor Sen Yung) and Birmingham (Mantan Moreland).

To lengthen the running time of the film, a two-minute prologue was added, detailing the workings of a bureau of missing persons.
