Whispering Smith is an American Western series that aired on NBC. Based on a 1948 movie, the series stars Audie Murphy as Tom "Whispering" Smith, a police detective in Denver, Colorado. Filming of the series began in 1959, but the program did not air until May 8, 1961, because of unexpected production problems.

Whispering Smith combines elements of CBS's Have Gun – Will Travel starring Richard Boone, NBC's Tales of Wells Fargo starring Dale Robertson, the syndicated Shotgun Slade with Scott Brady, and ABC's The Man From Blackhawk, a Stirling Silliphant production starring Robert Rockwell. While the setting of the series is unique, it is otherwise a standard detective program.
