Chicagoland Mystery Players was a live television series first shown on local station WGN-TV in Chicago starting in 1947, then picked up by the DuMont Television Network and first aired on the network September 11, 1949. The 30-minute show aired on Sundays at 8pm ET.

The series was one of several on DuMont that began in a local TV market before being picked up nationally. DuMont dropped the program on July 23, 1950, and it's unknown if it continued in Chicago for any time.

When the series aired on WGN-TV in Chicago, viewers were not given the solution to the crime. Instead they were told to pick up the next day's Chicago Tribune to find out the solution to the mystery. WGN-TV was owned by the Tribune.
